Review title is Good when it works [SEP] I got this for my wife as she has been getting really good at doing her own dip powder nails at home. She started out with cheaper 20$ drills and I thought now she has the hang of it she could use a more professional one. I got her the green and she was so excited to use it. She charged it up so it was ready to use on her next manicure day. It comes with a USB charging cord, a cord to connect the drill to the power bank, and drill bits. There’s also a little plastic holder that connects to the main part of the device to hold the drill. She really likes the digital screen, it shows the battery charge, the power number you’re working with, and what direction the drill goes. There is a power button and a reverse button and the screen has a dial around it to move change the speed setting which goes to 30. To insert the drill bit, rather than just pushing it in like on the cheaper drills with these you twist the bottom of the “pen” open, insert the bit, and twist it back to lock it again. She noticed immediately how much stronger it was even in the first set. She was easily able to turn it up to about a 3, however, as she was using it she noticed it started to slow down and after using it for a minute or two it would stop and say there was an error. This happened at least 3 times during her manicure which seems odd and unreliable. If it weren’t for that she would love it but it did kind of lower her opinion and rating of it as she couldn’t figure out why it kept happening.
