Review (4/5): Nice for the price and perfect for travel!
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.
It comes with 3 replacement files and a small dust brush for easier clean up.
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.
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.
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.
