I started off using CG, and I loved them. I was getting two weeks out of a manicure which I think is pretty good! I loved the whole system, including colours and topcoat.
However, I now find I am moving away from them as some of them have started to become a little gloopy, especially my favourite colour. Too much air exposure I think, so anyway I have started to move towards CND colours and also some OPI, as OPI is what I used to use when I was a normal consumer and some of those old colours are still as good as new when using on myself.
I also had moved over to Lumos base and top to find out why it was felt to be so amazing. I havn't looked back since using this!
