I really like this Essie top coat! Personally I like to use normal nail polish on my toe nails so it's easy to change for occasions and gels on my fingers.
This top coat definitely makes a difference in the longevity of normal polish and also keeps it from chipping! I've used it now over both Essie and OPI nail polish shades and the formula didn't change on either base and lasted really nicely for around a week on my nails with no chipping before changing to a new nail colour underneath.
I'm always looking for a good top coat and I really like this one. I tested it over a red Essie polish and it lasted about 5 and a half days before any signs of chipping.
I'd been wearing polish by itself for a while because I'd run out of my previous top coat and it just wasn't lasting too well. I find polish chips on my nails easier than others, but this top coat helped a lot. It also gives a great shine and dries fairly quickly. I'd definitely recommend it.
