This is, hands down, the best quick-drying top coat I've ever tried, and I've tried MANY – OPI, Essie, Seche Vite, various indie brands, but this one beats them all.
I was terrified when the old Top Gel disappeared, but this works just as well, so I don't know if it was just a name change. It dries quickly (no lamp/light needed), gives a beautiful shine, is super affordable, and doesn't suffer from the problem of the polish shrinking on the nail when drying like many other quick-dry polishes do. If this ever gets discontinued, I'll need to stock up backups for the rest of my life :D
