Review (2/5): Sadly not worth it.
The first time I used it, it worked perfectly! Now the second time I just tried to use it, it would stop & start sporadically & then I almost couldn't get it to start back up again and I still had 4 nails to go! The bits and manicure kit are nice & I love the shape & weight of the drill, however I do not appreciate it's unreliability. So I'll have to find a replacement before I did my nails again.
