This is a great, inexpensive quick-thickening mascara! My lashes seem to be getting sparse as I age, and this mascara plumps them up quickly and easily--the brush separates nicely, and one coat leaves my lashes looking full and dark. I'd compare the formula to perhaps MF 2000K, Almay One Coat or even Maybelline Full & Soft as far as one-coat thickening power goes; however, this mascara left me with much fewer clumps, flakes, and smears by the end of the day than either of the above 3 mascaras. Even with my oily skin there are no racoon circles by evening, and *that's* a rare thing. I'm hooked!
