Review (4/5): Good and strong.
If you can handle a high-powered drill for your nails, then this is for you. It works well but should have a slower settings and also less strong. It took me a while to learn how to do it without loosing half of my cuticles. The attachments are many. Once you master the art of how to use a drill for nail filing, then you can finish all your nails in 5 minutes.
