Review (4/5): Not too much
I was afraid after reading reviews of other shavers that I would mangle my hands with one. Some reviews of this item said it would not have that problem and thankfully my hands are still useful. The blade seems plenty sharp as long as you use it as soon as getting out of a shower. If I wait even 10 minutes or so it just feels like I'm cutting stuff that shouldn't be cut. My only knock is that the skin seems to accumulate behind the blade. Maybe this is a problem with other shavers as well, I'm not sure. I find myself shaving some and then turning it around to clear off the skin chunks and then going back to work.
Overall I'm happy with it and have recommended it to others.
