Amazeballs! I put it over any & all polish and get a week!!!

This stuff is so good. It has replaced Essies own Good To Go as my holy grail top coat. Now, I don't use it with the matching Gel Coture polishes, I just use it with my original Essie, OPI, SinfulColors etc... and have no issues. It works with all polishes. I love how this top coat makes my nails feel hard and sturdy. It definitely increases the durability of my manicures, and as someone who is hard on my hands, I love it. It prevents chipping and tipwear. It dries fairly quickly, despite not claiming to be quick drying. It also has an incredibly shiny finish. The shine remains throughout the duration of the manicure too (which is usually 5-7 days with this top coat), so I don't have to add extra top coat for extra shine. The polish applies easily too, with no dragging. I love this top coat and highly recommend it. I will definitely be repurchasing when I finish my bottle.

I have used every type of polish and topcoat. This is definitely the best formula for longer lasting nail manicures. Mine don't last a week, but compared to my usual one to two days, this polish lasts about four days!

This top coat shrinks at the tips causing peeling.

When I use this in conjunction with another Essie Couture nailpolish, it definitely lasts a week. When paired with another nail polish underneath, there is a lot of shrinkage. Overall, this is one of the best topcoats I have tried (and I've been through MANY). It leaves my nails really shiny and prolongs the wear of the nail polish. I can deal with the shrinkage since the other benefits are quite strong.
