Hi Misty, I am a Pronails Geek and have had training in the use of an electric file. I find that it definitely speeds up the process of removing product from the natural nail if used with care but you will find loads of geeks on this site who are not happy with the use of efiles and they are often referred to as drills. Each to their own opinion however. The course which is offered with Pronails is very reasonably priced, however, if you do a search and type in 'electric files' or 'drills' or type in my username and the heading 'Drills, drills, drills, Eek!' you will find a thread which I started with plenty to say on the subject. Lots of differing opinions on that thread which you may find useful and be able to form your own opinion. HTH.
