I have been doing my own nails for years but more recently in the past two years have become more serious with it, meaning I've invested more into it than just some nail polish colors. I stopped getting acrylics at the nail salon because of the cost but missed them terribly so decided to do them myself. One of these drills is completely necessary for getting the job done but I didn't want to spend $500 on a professional Kupa brand drill so I began researching and reading product reviews. I finally settled on this one because it had good reviews, wasn't "cheap" but also wasn't going to cost a fortune. Since I only do my own nails the machine will not be taxed the way a nail tech's drill would be. I've only used this machine twice so far but it is comfortable to hold, not too heavy, and performs smooth but with plenty of power. And I love the fact that it has the twist and lock chuck, and uses the standard size drill bit.
