a lot of power for really bad feet [SEP] i am going to confess something my feet are hideous my family make fun my feet all the time and call them barney rubble feet i basically walk around barefoot almost and never go for pedicures i would go for a pedi but i am too embarrassed at how bad my feet were i will be the first to say i neglect my feet they are or should i say were very callused and stained my heels had deep cracks from neglect and three years of being barefoot almost exclusively today my callus remover came and i have to say i am impressed i shop on amazon alot and it takes a lot for me to go out of my way to write a review but this gadget deserves onefirst out of the box it looks to be a heavy duty machine thick power cord and a decent weight but not cumbersome it looks built to last it has enough power on low to do a major overhaul on the hardest and deepest of calluses user beware this thing packs a punch do not spent more than a couple seconds on an area or you will feel the burn quick try just tapping the head on your calluses go against the direction of the spin because it will run off on you it is strong enough to sand down thick toenails too my feet have never looked this goodno worries for lack of power on this thing if you are looking for a gentle buffer this is not it so if you feet are in decent shape look for something a little less aggressive if your feet look like they walk over hot coals from time to time this baby will take care of that in one quick session my feet are super smooth and look like brand new albeit a little sore
