Review (3/5): underpowered
The waterproofing is excellent. It cuts your beard and hair but it is way under powered and will actually bog down if you push it like a normal shaver. II have to run it over the same spot 4-5 times to get a decent shave. What you get in the ability to shave in the shower is a trade off in time and not being able to save any time. I gave it 3 stars because it could be 5 with just a little more power to actually save time.
