I purchased this because I scored a really great deal on Almay mascara but as soon as I started using it I realized it wasn't worth using. It didn't really have an issue with clumping, it was more that it didn't add any length, depth or color to my eyelashes. After applying all my makeup it still looked like I was missing my mascara. Or that I had dipped the brush is water instead of mascara. If you like that "no makeup" look, than this is the mascara for you but I want definition to my eyelashes because mine are naturally light and this didn't darken them at all. I threw the rest of it away because I didn't want to waste any more time applying useless makeup. Performance Didn't do a single thing for my eyelashes. From close up with a mirror, you could tell that they were a little bit darker after applying it, but from far away it looked like I had no mascara on at all. Ease of Application It applied nicely, no clumping or anything like that.
