It promises "300% more volume".... I was skeptical.
Here are my results:
I felt like it really gave me length and volume. It didn't flake, clump, or smudge, but I felt like it was really light/thin. I don't know why, but I like a really heavy mascara now, and I didn't before. Some of my lashes were sticking together (I really need to find my lash comb!!) I think it's a decent performing mascara though; I didn't see any problems with it.
