Terrible. It didn't hold a curl at all - almost all mascaras hold a curl on my lashes. The formula gave me droopy, saggy lashes. The comb brush made for messy, clumpy application. Also sucked the volume right out my lashes, which was really disappointing. The only good thing was that it made my lashes inky-black for about an hour after I first applied. I'm sticking with MAC Plushlash.
