This stuff is awesome.
I exchanged the awful CG Fantastic Lash (DON'T buy it--read my review if you want to know why it was so bad) for this one after reading some other reviews.
I bought it in Black Plum--the color looks really purple and shimmery on the wand, but on my lashes it just looks black (which I liked b/c I didn't want something too drastic). The best thing about it is NO CLUMPING! My lashes are fairly thick so this was really important to me. The wand's unique design does a really good job at lifting and lengthening my lashes. It's also very light--not globby or sticky--and doesn't bother my eyes at all.
I wouldn't recommend this to someone seeking dramatic results, though--it's a good everyday mascara (choose something else for a night out).
But I LOOOOVE it.
