This is a pretty nice quick-dry top coat. I've used it several times now and in my opinion, it works as well as Seche Vite and Poshe quick-dry top coats when it comes to preventing chips and tip wear. It is not as thick a formula as those other two, so it applies easily, but might take a tiny bit longer to dry. Like with other top coats, I applied this over still-wet nail polish. I can't say anything about its claims to prevent yellowing polish, though. I never really notice yellowing as I tend not to wear pale/neutral polishes.
