I'm not very experienced doing my nails yet and this is my first e-file so I don't have much of a basis for comparison, so keep that in mind. I've had nothing but a great experience with this. It's worked perfectly according to what I'd expect. I can control the direction of the rotation of the file (important, trust me), and the speed can be very slow for careful removal of cuticle or very fast with a highly gritty sanding band to remove bulk project. I've used it MANY times so far and it's worked consistently well.
