I got this to replace the last electric foot file I had, because the motor in that one recently just stopped working for some reason. This one seems to have a strong motor, AND a great battery life. I’ve used it 3 times since I got it and it still hasn’t run out of the charge it had straight out of the box. It comes with sanding pads for the flat bit, which files a large part of your foot at once & those are gritty but not where they’re uncomfortable to use. It also comes with a mandrel bit with sanding bands for smaller areas and works great. The only complaint I have, which is not just exclusive to this product, is the length of the charging cables these companies give you. They’re entirely too short, oftentimes not being long enough to even sit on a table while being plugged into the wall. I wish they were longer, but at least they include one! 10/10 recommend this product!
