Review (5/5): A good buy
My big toenails were thick and partially black from fungus. I tried to sand them down with a regular nail file but that was way too much work and too little progress. I was a little doubtful about this drill because of the price but it really does work. If you press down too much the drill does stop but the whole point is to really not do that, lightly sweep it over your nails and let the sanding do the job. I like the speed dial and the fact that I can control it. For the price, it does what its supposed to do. I didnt have any overheating issues or anything. Now my toenails look as good as they are going to get while i do my treatments.
