Review (5/5): Using to file my Smile retainers
This is a fine product for the purpose I purchased it for. I would not recommend this item as a heavy duty nail filer. I use it for filing the bottom of my feet and it makes them very soft and smooth. I have had pretty thick calluses on my feet and this did a wonderful job on them. Using a different head attachment, I also use it to file down the top edges of my Smile retainers. They come with pretty substantial edges that can cut into your gums and tongue. This is an easier way to file down all the edges so they are very comfortable to wear instead of using a hand file. The machine doesn't have a lot of torque so it stops under any pressure at all. Would recommend only for light filing of nails/hands/feet.
