a very poorly designed product that does the job [SEP] what a terribly designed device whoever drew it has likely never used itthe devices neck curves inward plus the roller is only partially exposed about of its surface when it could be 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 handsyes it scrapes dead skin away but it is 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 chargingthe 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
