This razor really does improve your shave. I'm baby smooth for a full day and half, as opposed to half a day. It's not a gimmick, even if it sounds like one.Now for the bad news. I've been through 3 of these and the piece of junk button that switches the motor on and off broke on all three. It starts with the thing not turning off easily. Then it won't turn off at all, so you have to take the battery out every time. Then water gets inside and rusts the contacts and causes excessive battery drain.I know the thing works though, because when I'm too lazy to put the battery in, the shave is noticably less close.So basically, great concept. Terrible flawed product. If you can afford to replace it once every few months, it can't be beat.A much more minor complaint is that the on/off button is exactly where I put my finger when I shave, so before the button breaks, I often accidentally turn it off.
