I paint my nails quite often and I used to use an expensive salon quality polish and I wanted to find a cheaper alternative, so when I saw this for so cheap and with so many colors I had to try it. I wasn't expecting it to be that great of quality but OH MY GOODNESS was I surprised. This works AMAZING, I will never go back to my old polish. I can keep this stuff on for almost 4 weeks, and if I didn't peel them off when I wanted to change them or if I thought they were too grown out then I think these could even stay on longer than that!Some of the other reviews say that it peeled off super fast, but that might be because they aren't doing them right. As long as I file them and put enough layers on, and let them completely cure before adding a new layer, than they work great!One thing I noticed was that the colors were slightly off, but nothing major and I was still l super happy with how they looked. Also one of the blues has a sparkly sheen to it, but once again nothing major.One thing i wish would change about this is the size of the top and bottom coat bottles, there isn't enough of it, and I'm almost running out. But that might just be because i use it a lot and make my nails really thick...Overall I would 1000000 percent recommend this product or anyone! just make sure you do them right and they will stay on great!
