I've been using the Panasonic Arc IV for about six months. Before that I had used a blade for a year after growing frustrated with my older electric, a Braun.
The Arc IV is awesome. Used dry, it's better than any other electric I had used in the past. Used wet, it's nearly as smooth as shaving twice with a blade (to get my smoothest shave with a blade, I always had to shave once down, relather, and once up). It's much smoother than shaving once with a blade, and far smoother than any other electric dry. It's much less likely to nick, and I seem less prone to bumps.
I shave in the shower. My process is to wash my face in hot water. I then apply conditioner (Trader Joe's hair conditioner with tea tree oil) and let it sit for a minute. I rinse that, apply shaving cream, and shave. It's a great, smooth shave every time.
I couldn't part with it. It's the first home shaving experience in my 22 years of shaving that's left me truly pleased.
