Review (4/5): Gets the job done.
Works with regular shaving foam if you don't want to use the pricey Nivea cartridges, has no problem getting wet in the shower. This is what I needed, and what I got. The shave isn't as close as a blade, and you'll want a mirror if you use it in the shower. The battery life is fine and the device styling is a little nicer than that of most electric shavers.
