Rated 1 out of 5 by from Chips Quickly I bought this and used it with Julep polish and the Go the Distance top coat. It wasn't even a week before my polish started chipping. For the price you pay for these products, they should last a minimum of two week. My cheap Sally Hanson base and top coat last weeks longer than these do and cost a fraction of the price.

Rated 2 out of 5 by from Good at first but doesn’t last long When I first started using this I loved how quickly it dried and how I could tell when my nail looks matte. But by the time I got through half the bottle it started to get thick and clumpy. And there would be dried bits that would get painted on my nail that makes it uneven. Once it got to that point i had to make it my toe nail base coat since I don’t care as much if it’s not as even. I’d say it’s okay to buy if you paint your nails enough, but for my once a week mani and biweekly pedi I’ll stick with something that will have a longer shelf life.

Rated 5 out of 5 by from Goes on smooth It goes on real smooth and fills in my ridges. I tried it with one of the black metallic polishes and it did NOT stain my nails. Plolish didn't chip like it does sometimes with other polishes.

Rated 5 out of 5 by from Perfect first step! This base coat made my nails noticeably smoother, it dried quickly, and prevented any staining from the nail polish color. A super first coat!
