I always use a fast drying top coat when doing my nails as I can't sit still (nor do I have the time to, unfortunately). I typically use Seche Vite, but it had twice become too gloopy and I had received this one as a bonus when ourchasing a polish, so I gave it a go. I actually really like it. It goes on smoothly, leaves a moderately shiny finish, lasts a few days, and does not "shrink" (as the seche vite can do as it gets old). It does, unfortunately, have an insanely strong odor that worries me a little bit, so I take care to not inhale when applying. It does not dry as quickly as the Seche Vite, but it does dry rapidly nonetheless. I feel like I may repurchase this, but the strong fumes do give me a little pause. I will continue to look for a favourite rapid dry top coat.
