I have used the Targus and its good, but I also have a D-link and a Linksys that are much more durable and have 6-8 ports. Too many gadgets for a 4 port!
I have the Dlink in front of my main computer because the ports face the front for easy access. I have it stuck to my monitor base with self sticking Velcro so I can plug and unplug one handed and still remove it if I want.
The Linksys is hooked up to a laptop in our familyroom family room where I seldom unplug stuff.
stuff. The ports are on the back while the lights are on the front...Looks much neater, but not so handy.
