What I love about Kleancolor nail polishes is that they have a huge variety of colors. The formula isn't too bad, but not the best I've used. There were a couple of things that bothered me. First of all, they have a pretty harsh smell compared to other polishes, especially their glitters. Second, I had a couple of cases of wonky and split brushes which I couldn't fix at all. The brushes are nice and wide, but way too thick for my preference. They pick up too much nail polish and you might end up with cuticle flooding if you aren't careful enough. The third and last thing is that the formula isn't very much chip resistant, so don't expect very long lasting manicures.
