Review (3/5): Not very powerful
[[VIDEOID:a9343ecf3ac0b76f3c3f1156cafb9e89]] This foot filter is easy to hold, and I really like that there are three different grained heads that rotate, but stay attached. You don't have to constantly change the heads on this.
However, when you rotate the heads you have to hold down a button on one side and then use the very small rotater to change heads. It makes it a bit difficult to change the heads.
Also, I had problems with it constantly stopping while I was using it. And my calluses aren't even that bad. If you just have a bit of dry skin this will probably work for you, otherwise you're going to want to skip it.
