nice for the price and perfect for travel [SEP] nice for the price i am not a huge fan of these when they are fully battery operated because you have to buy batteries rather often this one takes aa battery not included it takes some force to pull off the bottom portion to add the batteries best to use good quality batteriesit comes with replacement files and a small dust brush for easier clean upit does file feet and calluses just as well as their rechargeable counter parts if you have really bad feet like i do your feet will not be made smooth and soft just with this but it will not with the version either it stops if you bare down too hard so you cannot hurt yourself it stops if something gets stuck in it i caught my pants and it stopped right awayi would recommend this to folks who only need it on occasion personally i need mine every couple of days so at home i will stick to my rechargeable but this will be perfect when we go to the beach or mountains that way i do not have to keep up with yet another charging cordi received the ovinna callus remover free to test and give my honest opinion and review my review is based on my personal thoughts and experience
