meh...
I really liked this because I wouldn't have to soak my whole fingertip in acetone. It was a little slower than I could do soaking in a acetone with a heated bowl. Sometimes it would heat up hotter than other times, and the directions weren't super clear. I've used this probably every other week since I recieved it in Dec 2017 and now the button is starting to melt/break. Don't think I will repurchase.
