I wasn’t impressed. A couple of times I had to ask the technician to stop as I was getting heat spikes from how hot the drill was > her response one of the times was that my nails were too soft 🧐 Not that the speed needed adjustment, or that she was constantly going over one spot, instead of letting the acetone do its job. In this case I felt rushed. I only went because my usual place was fully booked; I won’t be returning.
