This is my very first review, but I'm compelled to write one after using this mascara. I've been on a drugstore mascara hunt for years and finally found my favorite one! This product is wonderful! It lasts all day, and even though my tube doesn't say 'waterproof' it does appear to be waterproof. I've done an hour long workout and taken a shower and it didn't smudge at all, I had to use actual makeup remover to remove it. It lengthens and volumizes with no clumping. The only one that is comparable would be Maybelline's Full N' Soft (which was my HG for years.) I think I like this one just a slightly bit more!
