Does what it's supposed to.
After my mastectomy, I was advised to not use regular razor to shave my underarm.  This was the perfect replacement.  I also use it for facial hair, no more red rash from waxing.  If I have one criticism, it's that occasionally there is no power when turning it on; so far have been able to fix this by squeezing and pushing on the top.
