I was extremely happy with my CND Rockstar manicure. The salon is small and basic, but the welcome is fantastic and genuine. The therapist used meticulous technique and did a great job. She did not remove the existing shellac by soaking my whole hands in acetone or by filing it off or even grinding it off. Also, I don't know of any other place where you can get the Rockstar manicure - really glittery!
