I did a Gel Nail Polish Review HERE about all the different polishes and which are my favorite. One of the commenters asked me if I had tried the CND brand. I am in no way paid by any of these companies; I am just a random person who wants to find the product that works the best for me. So I saved up and bought CND Shellac Base Coat, CND Shellac Top Coat, OPI Bond Aid, and CND Color Coat, Masquerade. I also read a review HERE from one of my favorite bloggers, and she also uses the CND brand and says it works the best for her… she does cross fit too. I have issues with being very rough on my nails. I cook, clean, wash dishes, etc. and so far the longest the gel nails have lasted was 5-6 days without an bubbling, chips, or lifting. Until now… Oh and by the way, I am not a professional.
