Advice needed please; I'm looking to invest in some gel uv polish. I want one that's not too expensive to buy, has a good range of colours, lasts and is easy to take off. If be greatful if anyone could make suggestions. I know there's quite a few, I was even advised to try some of the cheaper ones from eBay like bkuesky, cco etc which look just like cnd shellac just different writing on the bottle. They're very cheap so not sure if they're too good a price to be any good? X
