I can't even explain how GREAT their electric drill is. I wanted to buy this drill for years, but since it was more expensive before($399.99) i never bought it. I was still using cheap generic drills, and it would cause friction which means my clients felt warm sensations on their nail bed. After using their drill, I REGRET not owning one all these years. It saves so much time, and the drill fits so nicely in my hand. It's a great machine!! My clients love it and have all pointed out how much more comfortable they feel. It saves time removing gels as well!! I actually think this is a MUST BUY for all nail techs. It's actually similar to machines they use for dental work, and it's portable too!! Don't forget to purchase bits, especially the round gold bit since it's not included.
