Review (5/5): Very happy with this!
I LOVE this thing!! Have used it many times and it work great. Has forward and backward controls and lots of connections . I use this to take off the gel polish on my nails instead of filing, a much better, smooth result. It is more difficult to do it to yourself, so just be careful to avoid the skin and avoid going over your actual nail with some of the harsher bits as it will thin the nail and also it can get hot and burn your nail bed.
