Review (5/5): Not clumpy
It lengthened and darkened my eyelashes nicely without clumping, and didn't smear when I rubbed my eyes. I normally have to break up at least a few clumps to keep from getting that "spidery" look with my normal mascara that has the same sort of brush, and I didn't have to do that at all with this one. A few quick swipes and I was good!
