THIS WILL RUIN YOUR NAILS! As other reviews have started, the polish lasts a long time without chipping, it's shiny... Blah, blah, blah...at first that's all true. Here's the real bottom line: this stuff will damage your nail beds! After a few uses I noticed the polish was harder and harder to remove, that base coat wasn't going to budge. I also noticed that the edges of the polish were peeling up regularly. After 4 rounds of using this system my nails are brittle, scarred, peeling, and yellowed in spite of using the base coat. I think it has dehydrated my nails. I compare my nail beds to the scarring you'd expect after soaking off salon gels or acrylics. I can't wear polish now because even with a ridge filling base coat my nails aren't smooth. And without polish they look awful. Bottom line: it's just not worth it.
