I am IN LOVE with this base coat! Normally I have to change my nail polish every other day because it chips and it will leave me with slightly stained nails (even though I had a base coat underneath it), but with this as a base coat the polish never comes off! My nail polish tends to last for a good week when I use this (along with a top coat), which has never happened for me before. I feel like I'm not experiencing any more issues with my nails getting stained, and my nails aren't peeling like they sometimes do. I think I finally found a winner in this base coat!
