I am on my feet alot for work and some of my home projects. My feet get abused and negelcted sometimes. This little callus remover is nice. It is recargeable and comes with usb power cord. 2 heads a coarse and fine grade drum that are easy to change. And a cleaning brush. If you follow the enclosed instructions It works the best. Cleans away the dead skin. #rankboosterreview #sponsored #ZoiyTop https://www.amazon.com/Electric-Rechargeable-Electronic-Pedicure-Calluses/dp/B075YSKY3J
