I have a collector car I won't drive in the snow, so I'm forced to use a battery tender to keep the battery alive while it collects dust during the winter. In years past, I've used a variety of chargers/tenders (I also had a Harley I stored in the winter), but none has worked as well as the Xtreme Charge I've been relying on this last year. Though my battery used to die all the time within hours of being removed from previous chargers, it now holds a charge for days on end. I am certainly no expert. What I know about how the system works is from what I've read online. It's my understanding that once the battery's gotten a full charge from the unit, it switches to a "pulsating DC current" mode. Apparently this pulse technology does something to reduce and keep sulfate deposits from building up again.

What I know about whether the charger works comes from the old, off-brand battery that, by all rights, might have been relegated to the recycle bin last year but is still holding a charge like a champ. At about the same time I bought the charger, I had already bought a new battery for the '88 Rolls Royce Silver Spur. But rather than use the old battery to recover a "core" charge on the new battery, I kept it and used the Xtreme Charge on it, just to see what would happen. It brought the old battery back to life so well that today I use the charger to keep the old battery alive as a backup power source for my sump pump!

I really appreciate the charger's LED display, too, which provides a constant readout of the state of the charge. Makes it easy to monitor its progress at a glance. After it first reads the current charge, a series of small lights begin pulsing. As the battery charges, the display expresses the status as a percentage of full: 25%, 50%, 75% and 100%. Another great feature: if a battery is dead and cannot be charged, the display tells you bluntly "battery dead" (a situation I have yet to see *knock wood*). In years past, I would would waste time and effort hooking up more than one battery to a charger when it was simply impossible for the battery to take a charge. I went with Xtreme Charge's "marine" charger because it's water-proof and comes in a rubber casing. These days my battery is fresher in the spring than it is at the end of the driving season.

I started wearing these lightweight, relatively inexpensive zip-neck pullovers after I took an EMT-B course. It's less bulky than a sweatshirt, just as comfortable as PJs and very functional. There are two side, on-seam pockets large enough for your hands, a neat large velcro-sealing chest pocket, and a D-ring on the side for attaching a key chain or lanyard. They're very durable as the elbows are reinforced with denim. And they're widely available in three colors (navy, black & gray). Too warm for the summer here in the Northeast, but perfect for the rest of the year as an everyday pullover.

I've been using the previously-untried soft reading lenses for at least 10 years -- so long, I forgot how cool they are. I used to windsurf and would spend time at the beach repairing and maintaining gear while waiting for the afternoon thermal breeze to kick in, detail work that required reading glasses or Optx 20/20s on my sunglasses. I also used the same pair of sunglasses for driving, skiing and general daily wear. The glasses have to be wet slightly to get the 20/20s to stick, so it can be a little fiddly getting both lenses parallel and then squishing out the air bubbles without moving them around (also, if your frames don't have a rim at the bottom, it's more difficult to get them aligned properly). But once that's accomplished, voila! $300 bifocal sunglasses for just 20 bucks. Once they're stuck down on the glasses they don't move unless you mess with them when cleaning the glasses or if you get them wet. Peel them off with your fingernail if you change your mind. What could be simpler?

-- Evan Marks

I've used this, to great effect. With my prescription sunglasses that I always use when outdoors, I had a problem that I couldn't read maps while driving or hiking. Sticking on just ONE of these bifocal semi-circles was a total solution. The water adhesion has held for two years, and cleaning the bifocal part has not been an issue.

-- Stewart Brand

I've used these, but not in the intended fashion. I ride a motorcycle and wear a helmet (though my state doesn't require it). In my 40's I've started wearing corrective glasses, but during the day I also need some sort of eye protection from the sun. The solution was wear regular sunglasses and use these stick-on reading lenses. But I didn't care for them being on my sunglasses all the time, so I stuck them on the face shield of my helmet. This allows me to read the gauges on my motorcycle and the GPS. The field of view is quite small because the lenses are further out than intended, but it works better than not being able to read anything. I've since purchased prescription sunglasses and retired the stick-on lenses, but these work in a pinch and, IMHO, are on par with the $12 specials from the big box stores.

We've been using 3M's SOLAS reflective tape for several years. It was designed for the Coast Guard to use on life jackets, so you know it has to be tough and withstand time, bad weather and wet conditions (SOLAS = safety of life at sea). It is a bit expensive, but it is the brightest and most durable stuff I've ever found. We use it everywhere and have put in on just about everything: garbage cans, walking sticks, jackets, kayaks, a bicycle, a stroller, a trailer, traffic cones, automobile door jams (so oncoming traffic sees me right away), the trunk of my car (an instant safety device if I get stuck on the side of the road) and the car's mudguards. The strips on our mudguards -- which take a lot of abuse! -- are still sticking after more than seven years. Now that I've seen how effective it is, I really think it should be a law that all cars come stocked with reflective stripping on door jams.

A few years ago when my wife and I renovated our home, we found inspiration in some unusual places. But perhaps the oddest of all was AW Direct, a mail order catalog that sells parts and equipment for tow trucks. While browsing through the catalog one day, I noticed AW Direct offers a recessed aluminum step designed for use on service vehicle bodies. But when I looked at it, I saw something different: a soap dish!

We bought one and installed it in the shower I now use daily. This is by far the best-designed soap dish I've ever used. The open front allows water to drain away easily, while the diamond-plate surface secures and elevates the soap so that it dries without creating a lot of yucky soap-gunk. And of course, the aluminum doesn't rust or corrode.

We ended up buying quite a bit from the AW Direct catalog for use in our house, and I heartily recommend it if your domestic tastes gravitate toward the functional/industrial. In the home or on the highway (or vice-versa), AW Direct delivers!

Why sacrifice style for safety? Subhead grip stickers are an attractive, very effective, functional alternative to regular, boring, anti-slip tape. For the last year, I've been using the star-shaped stickers on some wooden steps outside my home. Just recently, I affixed the skull stickers to some rattan sticks I use for martial arts. And in the near future, I'm planning to add some fleur de lis stickers to some other steps. High foot traffic areas also experience a lot of visual traffic -- walkways, pool decks, boat decks, ship ladders, etc. Most anti-slip tape is that boring rectangular stuff, long black or yellow grip strips that, to me, sometimes look too industrial or institutional for a home, garden and even some businesses. Instead, these come in fun, eye-catching designs that will also draw people's visual attention, potentially making it even more effective than standard rectangular anti-slip tape. I imagine some people would prefer to make homemade stickers/designs, but quite honestly, I lack the dexterity, patience, & hand strength to be able to create detailed, attractive & consistently-sized/shaped stickers (ironic given that I practice martial arts, I know). Still, I am certain if I tried to make the stars, my versions would look like an injured sea star or Dali-inspired Rorschach blots. It's much easier to just click and buy these.

These days there's a glut of first-person reportage centered on alternative lifestyles. Some narratives come across as self-righteous and self-indulgent. This book is not one of those. When 30-something journalist Doug Fine buys a plot of land in New Mexico and vows to live as "green" as possible, his self-deprecating, humorous outlook kicks in. He never denies he's in over his head. Quite the contrary, which makes every misstep and subsequent triumph all the more gratifying. From rearing goats found on Craigslist to garnering rainwater harvesting tips via -- what else? -- http://harvestingrainwater.com, and Googling a VegOil auto mechanic, Fine's journey is exactly what it professes to be: "green, Digital Age living." No substitute for the rigorous how-to's penned by experts, this entertaining, heartfelt journey is a testament to what's possible with a Web connection and heaps of determination. Indeed, the path to alternative living truly begins at our fingertips. Even if you could care less about going green, living local or starting-up solar, there's inspiration to be had. Plus, delicious recipes highlighting some of Fine's homegrown stuffs.

I'm a technical theatre professional, and being able to tie the proper knot in the appropriate situation is critical to saving time and staying safe. For a number of years, I've kept several sets of the previously-untried Knot Tying Cards around for emergencies. I keep one in my messenger bag, one in the glove box of my car, one in my tool bag, and there's likely another one in the official junk drawer in the kitchen. While there are around 10 knots I use on an almost daily basis when I'm working, there are a handful of specialty knots I know when to use, but can never retain how to start (or finish) them. One particularly bothersome knot is the Trucker's Hitch. If done correctly, it will secure an unruly load in short order (and can be tied with one hand if you're dexterous). If you do one little turn incorrectly, however, It becomes a slip knot and won't hold squat.

That's where these flash cards come in handy. They have this and other bothersome knots, and the cards provide enough of a trigger that I can execute the desired effect. More often than not, when someone 20 feet away asks me to tell them how to tie a particular knot, I end up throwing the set to them. Much easier than explaining it! And they always manage to tie the knot safely. Not all knots are created equal, and knowing how to create and properly use a variety of them is useful for everyone. On the stage, though, a poorly-tied knot can quite literally kill someone. I've seen more than one "of course I know how to tie a square knot" load crash to the floor because hubris trumped common sense and basic knowledge.

That said, these cards are handy for those who already know how to tie proper knots, but don't do so every day and need a quick reminder. For the novice knot-tier, the previously-reviewed Morrow Guide has never been equaled, IMO. I once taught a knot-tying class to a group of high school theatre students. I provided a 50-foot piece of rope and told them it could become a ladder. I showed them the page in the book and let them have at it. In about 30 minutes, they had a load-bearing 12-foot rope ladder. You can't beat that!

Between being over 40 and having run 14 marathons, I have feet callused enough to require "dealing with" on a regular basis. The PedEgg is a microplane type set of blades attached to an egg-shaped compartment that not only makes it very ergonomic, but also collects all the lovely "stuff." Very easy to use while seated in the living room rather than precariously perched over a sink or wastebasket, or balancing in the shower on one foot. I've tried pumice stones, rasps, and the super coarse emery boards with no luck -- those all take forever to get the job done (and none has a built-in mechanism to capture the shavings or dust). I thought I'd found the perfect answer in a microplane kitchen grater (not something most people would admit, since it makes guests wonder what other kitchen utensils have been pulling double duty).

Now that I have the PedEgg, the grater has been retired, officially. I use it about once every 2-3 weeks when there's 1/8" or more callus to remove. It leaves a very smooth surface. Surprisingly, it's more aggressive than the fine microplane I had. And you can buy replacement blades should it ever wear out. It also has an emery board on the outside of the cover for final smoothing of your feet. Overall, I'd guess the PedEgg is at least twice as fast as the microplane and four times faster than an emery board on dry calluses. Of course, if you work on your feet after a shower when they're soft, any of these techniques are faster.

I've been using this 9-tray dehydrator once or twice a week for the last three years to make dried fruit, veggies, jerky, dog treats, and dried bread crumbs. Other uses include re-crisping crackers, cookies, and chips, and thoroughly drying wet photographs and flowers.

Overall, this is truly the most flexible dehydrator I've found. The thermostat is adjustable (85-145F), so you can customize your dehydrating. The removable trays allow you to experiment with sizes, quantities and varieties of foods sorted by temperature range. If you group shorter-term items by tray, you just remove those trays first, then keep the remaining items/trays inside a bit longer.

Other units heat unevenly from the bottom, require you to manually rotate trays, and -- in the case of cheaper units -- don't let you control the temperature. Along with a thermostat, the Excalibur has a fan that distributes heat more evenly; it also features a timer, so it will automatically turn off at a desired time whether you're around or not.

All of the dehydrators I've used generate noise (I now use my Ronco and Home Essentials models exclusively for making dog treats). Since the Excalibur isn't quiet, I keep it in our craft room. It's very easy to clean. I enjoy not throwing out spoiled food. We always have healthy snack alternatives for us and our grandkids -- and they enjoy contributing to the process as much as they eating the rewards. Ever since we moved to a property with grapevines, they've helped us make copious amounts of raisins.

Tips:

1) To make fruit yogurt leathers or work with items high in moisture content, you'll need ParaFlexx non-stick drying sheets. Excalibur provides a pretty good guide on how to work with different foods.

2) If you buy direct from the manufacturer, it may be slightly more expensive, but I understand they'll guarantee the unit for 10 years; otherwise, you can purchase a 10-year extended warranty.

-- Chris Lewis

I have experience with both the Excalibur and the more recently-reviewed Nesco, a smaller and less expensive dehydrator. The Excalibur is a superior product if you are a heavy user and tend to be drying large batches of produce at once. It has quite a bit more capacity due to the design (no center hole and square racks make a big difference). The horizontal airflow system does dry large batches more uniformly. Although you can add racks to the Nesco, it dries less efficiently, and once you add in the cost of extra racks you are approaching the same price as the Excalibur.

Having said that, the price on the Nesco has really dropped and the top-down heater/blower is a nice upgrade over the older bottom-fan models. Heck, you could almost get three of them for the same price as an Excalibur, although that would take up a lot of storage space and use more energy to power 3 units.

Mistakes are NOT inevitable, but the logical consequences of remediable design. As such, it's so much easier to avoid them than to correct them, especially if each one becomes a link in a chain of events that go off the rails as a result. If I'd continued in academia, perhaps eventually chairing a department, I'd buy as many copies of this book as there were members of my department -- faculty, residents, nurse anesthetists, medical students. It's slim (72 pages) and easy to understand -- no formal process(es) to follow. Instead, the book provides several seemingly simplistic but very useful rules of thumb anyone can adopt. As Chase & Stewart write: "You don't need a Ph.D. in statistics to apply it. In reality, mistake-proofing is more like a structured form of common sense." For example: "The key to creating mistake-proofing devices and procedures is not to do too much at once. Instead, concentrate on clever, inexpensive methods to check for only one mistake at a time. If you have two possible mistakes, develop two separate devices or procedures to catch them." Right on!

The best way to ensure the detection of a mistake is to make sure that something in the environment makes it very obvious that one has been made. A good example of an environmental cue is the inevitable "extra" parts that remain after a do-it-yourself repair project. These parts make it very clear that you have not reassembled the item correctly.

Remember that the goal is to develop clever, simple and inexpensive devices. Don't immediately opt for the high-tech solution.

S-Biners are much lighter than conventional carabiners and have two attachment points, which really comes in handy when you need to quickly attach and detach things. When I stumbled on these at Frys recently, I picked them up right away. I'm a product design engineer so whenever I see a simple elegant design, I just have to get it. I now use a #2 for my backpack and a #1 for my keychain; I like to clip just my motorcycle key to my jacket, so I don't have to root through my pockets, and I also like to separate my car key when I take it in for service. The two attachment points really makes this easier. On a recent bike camping trip, we also used them in a pinch to hold my friends panniers in place. In addition to various sizes, S-Biners even come in a variety of colors. Just don't use 'em for climbing.

Since I seem to move house every six months or so, I have ample opportunities to test new strategies. This time around I experimented by putting plastic storage totes through FedEx Ground, and for the items I moved myself I used cardboard boxes with the addition of nonadhesive strapping tape and tubular handles. Much quicker and easier, less effort, no breakages, big success.

-- Charles Platt

Plastic Totes via FedEx

Wal-Mart sells them for storing items such as bedding and clothes in the home, but their semi-rigid construction makes them ideal for moving fragile possessions such as dishes and stereo components. They are stackable, waterproof, easy to pick up (recessed handle at each end), reusable (can be nested during storage), and will pass unscathed through FedEx ground. Best of all they barely cost more than cardboard boxes! My local FedEx-Kinko's was skeptical about accepting them for fear that the lids would pop off during transport. I allayed their fears by putting 2-inch tape around the perimeter of the lid and folding it under the rim. I had to make little notches in the tape so that it would seal properly either side of plastic strengthening ribs under the rim, but this was still much easier, quicker, and safer than using cardboard. Wal-Mart sells gray Sterilite brand totes (the type I prefer) through its stores, but not online. Models 1830 and 1835 are the ones I have tested through FedEx without any problems. You can pay a little more and get "latch totes" (models 1940 and 1945 with a flip-up latch at each end) but since you'll still need to add tape, I feel the latches are unnecessary. (NOTE: One reader pointed out that plastic totes may buckle if they are stored in a very hot place with heavy objects on top of them. I haven't encountered this problem myself, but I do follow the standard practice of filling each container to minimize empty space inside it)

Strapping Tape

If you still want to use cardboard boxes for items you move yourself, or if you are moving stacks of books secured with cling wrap (as I have suggested previously), consider adding half-inch nonadhesive plastic strapping tape. This is the stuff you sometimes see wrapped around boxes containing big items such as refrigerators being transported as freight. Often it's yellow in color. Shipping departments have a tensioner that they use to pull the tape tight, but you don't need that. You can get 3000 feet of half-inch strapping and a lot of little buckles, with a manual tensioner, for ~$45. You thread the tape through the buckle, pull up on it while bearing down on the box, and you have it as tight as you need it. You trim the tape near the buckle. The advantages are that it greatly strengthens the box while giving you something to grab it by, especially if you augment it with a handle (described below). Also you can link two or three boxes together so that you can carry them easily with one hand, especially up and down stairs. Much more efficient and secure than cradling boxes in your arms, less hazardous (you can see your feet and obstacles in your path), and less risk of back injury, since you don't have to stoop to pick them up. Note that FedEx and UPS don't like string or strapping that can snag their package processing machinery, so strapping is for transporting packages yourself or with assistance from movers.

DIY Box Handles

Make handles from half-inch plastic water pipe sawn into 5" lengths. My local Lowe's sold me six feet of pipe for around $3 and you can use any wood saw to cut it. You may feel this is a luxury, but if you want to protect your hands from the edges of the plastic tape, handles are nice to have.

Thread tape through handle.

Turn box upside-down and cross the tape ends.

Turn box right-side-up and thread one of the returning tape ends through the handle.

Add the buckle.

After pulling the tape tight, your box is now very easy to carry.

For the last year, I've loved commuting to work on this electric scooter because it's powerful enough to ride in traffic, but doesn't feel like a motorcycle. Before settling on the eGO Cycle 2 SE, I test drove a bigger bike and smaller one from a different manufacturer, but I liked the eGO best, which has turn signals in front and back, a headlight, and a horn. There are two settings: "Go Far" and "Go Fast." I find I can get up to 23 mph or so with Go Fast, though I usually use Go Far, which has a max speed of about 18 mph. The guy who sold it to us said it has a range of about 20 miles and takes about an hour to recharge. I keep it plugged in regularly and have not let it run down much since I got it. I am fortunate to have locked, indoor parking with an outlet at my work, so this is easy. My commute to work is 1.6 miles, but I have ridden the bike up to 10 miles with plenty of charge left. In Oregon, this qualifies as a bike, even though it's motorized, so it does not require a motorcycle license. I had not ridden a motorcycle before, so I had to train myself that "go" was controlled by my right hand and that the handle motion was toward me, not away from me (away was more intuitive to me for some reason). I wear a motorcycle helmet with a face screen. I prefer the protection while riding in traffic and like the face protection from wind, rain and bugs. I have ridden in light to medium rain but not downpours. In those conditions, I've found the traction fine and just slow down a bit. I have ridden only on surface streets -- in bike lanes or with traffic (the bike does not do well in gravel). Since I put a milk crate on the back, it's easy to haul stuff. I've noticed I get lots of thumbs up and smiles when I ride, too -- pretty certain they're directed at the bike. I remind my husband regularly that in addition to being a fun ride, it seems to be a guy magnet.

I'm an aircraft owner and use this very powerful LED-powered pen during night flying, but also while traveling on commercial flights and mostly at odd times: crosswords, fishing for something in the car at night, etc. The lighting and ink are independently controlled, so in addition to being effective, it's easy to use: the button on top is on/off for the light and the pen rotates to retract the ink. I've had some promotional-type LED pens in the past, but the button cells burn out and then it's difficult to replace them. This pen runs on a single AAA cell, which is easy to find and replace. The pen also comes with an extra battery and ink cartridge for $20 (with shipping) -- not too bad.

I never take my watch off, and this watch band has held up through two years of hiking, yard work, showers, swimming, etc. The original british grey nylon has weathered a bit, but the stainless steel hardware still looks great, and there is no fraying or visible wear on the tough nylon strap. I have the two-buckle version, but there is a a four-buckle version for extra security. The long tail of the strap doubles back through the keepers and stays out of the way. I never liked the way rubber straps feel on my skin, but the nylon in this band has never irritated or chafed.

I am a dermatologist and often take clinical photos of my patients with a digicam to add to their electronic medial records. With the Eye-Fi, a wireless 2GB SD memory card, I can take a photo and by the time I return to my computer the photo is waiting for me. Set up is very easy. You just plug the card in like you would any other memory card, do some basic configuration (the software works with Mac/PC) and you can send photos to the computer via the wi-fi you configure, or send direct to an online site like Flickr. You can also set the card up so several wi-fi are recognized (home or office, for instance), although you must program each individually. If you are using remote wi-fi access (that you have set up), needless to say, you will only be able to put photos online. In the office, we use the Eye-Fi to send to a local computer only. For someone with a built-in or USB SD card reader or Bluetooth, the Eye-Fi may have less benefits. For my purposes, it's spectacular. Previously, all patient photos would be downloaded as a batch and then each would be tediously attached at the end of the day. With the Eye-Fi, the photos are made available right away and they can be attached right when we write each patient's note. The flow is much better. Surprisingly, I haven't noticed any issues with the card draining the battery either. A few caveats: at any one time, one card can communicate with only one computer and one online site. You can, however, set up your account so your card can communicate with multiple computers. In order to switch computers, you go into the Eye-Fi manager on your computer and change the settings (i.e. if you're switching from work and home). While my use and situation may be unique, I also started my somewhat technophobic father-in-law on an Eye-Fi several months ago and it's been working well for him. Previously, he used to just fill up cards and then buy a new one (luckily, with the price of SD cards, that was still cheaper than film, but this is much better!). All he has to do is remember to keep both the camera and computer on, and the Eye-Fi enables him to share his photos online with us with virtually no trouble. At first, he had a few issues and concluded the card was broken. However, I showed him all he needed to do was make sure the computer was on with the Eye-Fi manager running (it can be set up to automatically run when you boot your computer). Undoubtedly, this technology has major potential to revolutionize digital photography as we know it. I look forward to future drivers that could support instant upload via any unlocked wi-fi your camera wanders near.

I work in the beverage industry and use this scraper for removing stickers from cooler doors that other guys with pocket knives, razors, car keys, etc. couldn't budge. The Trim 10 has wide, super thin, very flexible blades about 4 inches long that really conform to the surface of the work. I find it picks up more material per stroke and gets down to the bottom of things better than a single-edge razor blade. The holder has a very elegant folding design that allows for safe, touchless blade changes and compact, safe transport -- a much smaller, flatter package than a lot of utility knives. The scraper comes in a nifty case that holds a few extra blades, which can be purchased separately. A modular handle is also available for heavier work, but I never need it. I get mine from a janitorial supply company in Austin. I believe the scrapers are popular with window tint installers, too.

These durable cases protect your memory cards from getting wet, contaminated with dirt, or in my case lost. I have misplaced numerous memory cards due to their small size. With these cases not only do I not lose the cards, but I use the cases to organize them. The cases are small and compact (about 4.25" x 2.25") and only about 1" thick. They're available for almost all media types: SD/Mini SD, XD, Compact Flash and for MS (Memory Stick) cards. Each holds anywhere from 4 to 16 memory cards. I now use them to organize all of my media. So my wife has hers (I am not allowed to touch them since I have lost some of her photo flash cards), some for work (sorted by major projects) and then my own personal use cards. All I have to do now is grab the case I need for work, for instance, and I know I will have everything I need. These card cases have an o-ring seal Pelican says is "water-resistant." Though I wouldn't want to find out if they're waterproof, I think they only back off that claim to protect their tail. I have owned Pelican cases for my cameras for years and have found they're pretty much bulletproof. I also have one case for my laptop and use Pelican's cases for work to ship expensive equipment. My only complaint with their card cases is I wish that they had different colors to chose from so I wouldn't have to label them.

Kirsner gives you 21 different sites that pay videomakers and dissects the monetary deal each one offers. I haven't found anything as useful anywhere else. It is the equivalent of the first version of a "Writer's Market" for digital video producers. This list is free, part of a longer downloadable e-book he hopes you will buy, the Future of Web Video. I did; the rest of the book is a bargain for anyone serious about peddling a video of whatever length. I hope he keeps the list updated.

Every Mac comes with a long, bulky power cord and a small 2-prong nub. You can interchange them, but both are far from optimal for travel and field work (i.e. conference/convention blogging). Here's my fix: use a power cord from a Sony PlayStation. There are other cords that will also fit into the Mac power brick, but the PlayStation cord is easy to find. Where the Mac power cord is too thick to easily coil or toss in a bag -- and has a ground prong* so it's limited to those types of AC outlets -- the PlayStation cord is ostensibly perfect. It fits into the Mac power brick, coils up nice and small and has two prongs. Plus, you can leave your giant Mac cord at your desk back home and don't have to deal with dust bunnies every time you get ready to go out the door. I always keep one PlayStation cable stashed in my bag, so I only have to transfer the brick to the bag. This trick's good for any Mac laptop from the last 4-5 years, I'd guess, if not longer. In the last four years, I've used it on a 12 inch PowerBook, 13 inch MacBook, MacBook air and 2 MacBook pros. There used to be a video game where you had to fit shapes into brackets before an entire rig blows up. Can't remember what it's called, but that mindset is kind of how I first recognized the shape on the Mac plug.

*NOTE: using a ground prong is a safety precaution; although it's generally not advisable to switch to a two-prong, this has worked fine for me for years and if you're in a pinch, I highly recommend it.
