Review (2/5): A very poorly-designed product that does the job.
What a terribly designed device! Whoever drew it has likely never used it.
The device's neck CURVES INWARD, plus the roller is only PARTIALLY EXPOSED, about 1/3 of its surface when it could be 2/3 or more. It makes roller very inaccessible. You have to hold this thing at a very specific, AWKWARD ANGLE, which makes its usage frustrating, always having to reposition and switch hands.
Yes, it scrapes dead skin away. But it's not as strong as a proper corded one. Mind you, even with the cable plugged in, if the device is turned on, the battery is NOT CHARGING.
The two rollers it comes with are NOT COARSE like in the description. It takes quite a while to remove dead skin and the "shavings" coming off are/is actually a super-fine powder, finer than flour, almost like smoke, that floats through the air.
