Since I have gotten older it seems as if my feet stay rough with dry scratchy skin and calluses, I have used manual callus remover brushes but they are not very effective so when I bought this ZoiyTop Callus Remover I was amazed at how well it actually worked and how effective it was.
The tool is charged by a USB charger so no worries about having to continuously buy batteries to keep this up and running. It comes with two different head one of which is more course than the other so if you have super rough feet you will use the one with the rougher head and if you just need a little touching up use the less course one. It also includes a cleaning brush to keep your tool clean.
There is a light that lets you know if your tool is charged or needs to be charged, the green light will let you know it is charged and the red light lets you know that you need to charge your tool before using. The switch is a basic switch which makes it easy to use and less likely to tear up fast. Nice tool to have!
