I actually have a very similar product but I was very excited to try this one. I do prefer this nail drill over the one that I have mainly for aesthetics, and the fact that there is a drillbit holder. My previous one had a case that was separate and it could easily be lost, however these ones have drillbit holders and it makes it easy to switch in between the different heads. I also like that there is a light that clamps on to make it easier to see your work. This is definitely a very necessary part of doing DIY nails
