This Review Title is Nice for the price and perfect for travel! and the content is: Nice for the price. I'm not a huge fan of these when they are fully battery operated because you have to buy batteries rather often. This one takes 2 AA battery, not included. It takes some force to pull off the bottom portion to add the batteries. Best to use good quality batteries.<br />It comes with 3 replacement files and a small dust brush for easier clean up.<br />It 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 won't with the $40 version either. It stops if you bare down too hard so you can't hurt yourself, it stops if something gets stuck in it. I caught my pants and it stopped right away.<br />I 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 don't have to keep up with yet another charging cord.<br />I received the O'vinna callus remover free to test and give my honest opinion and review. My review is based on my personal thoughts and experience..There are other information for this review, one is This reviewer did not purchase it and the other is 0 people think this review is helpful.
