Review (4/5): This worked pretty well.
The product was left on for about 10 minutes. It bubbled up slightly, like it was supposed to. It didn't burn at all, it felt cold on the nails. It scraped off fairly well with a cuticle pusher. The one glitter accent nail came off on the first try, but the other ones had to be done a second time. Enough product may not have been used the first time though, so could just be user error. It caused no damage to the natural nails. Sure is quicker than soaking in acetone!
