Review (5/5): Great tool
Far better to use this tool and then a callus sander to remove thick callus material from feet. Formerly, i would use and entire battery charge to remove callus material from just one foot. This great tool makes quick work of calluses. I will admit you better be paying attention or you will draw blood. It also comes with 10 extra blades and a cuticle tool. I will probably never use the cuticle tool but it too is very sharp.
