This mascara was average at best. Not very volumizing, not very lengthening, just ok in everything but smudged badly.

I got this mascara as part of a 3-set of mascaras, it came in a washable formula and advertised "zero clumps" with definition and length. It has a plastic brush, which seems to grab a bit too much product, because while it coats all my lashes, it did clump and I had to go back over them with a lash comb. The formula washes off *very* easily, and is best if you want a short-term day mascara you can remove for night or you don't plan on getting wet. It straightened out the curl in my lashes, and does not hold a curl at all.
It's an "okay" mascara, but I wouldn't repurchase it. This one was a surprise for me, because usually I love Maybelline mascaras.
