I haven't used waterproof mascara in over a decade because it's difficult to remove and makes my lashes feel brittle and dry. However, I needed one to take with me on a beach vacation, so I bought this from CVS for $7.99. The curved brush is ginormous and bristle-y so it took some getting used to when applying to my very fleshy, hooded, monolidded eyes. It doesn't volumize or make my lashes thick and lush, but it definitely defines and lengthens my fine, puny lashes without any clumping. This mascara makes my lashes feel soft (not hard and brittle), and helps hold the curl, though my lashes do wilt a teeny bit after about 8 hours. Also, I haven't experienced any difficulties with removal (I use Cinique's Take the Day Off balm). The mascara is somewhat waterproof in the sense that I don't have black streaks running down my cheeks when my lashes get wet, but I do lose the curl and some flakies can be seen under my eyes. Also, even when my lashes aren't exposed to water, I will experience some smudging on my upper and lower lids. Overall, if I had to wear waterproof mascara, I would buy this again for it's readily available, reasonably priced, defines and lengthens my lashes, and holds the curl.
