Based on a review on Paula Begoun's website and on the low price, I picked up the Waterproof version in Basic Black. It was my daily mascara for a few months, so it obviously wasn't *too* bad.. it just wasn't quite good enough for me to want to buy it again. To give some context, my lashes are dark brown, average length and thickness. *Pros: Very easy and quick to apply -- just one swipe should be all that you need (but make sure to scrape some of the product off of the brush; see con #1), and it dries fast (since it's rather dry to begin with). The length and thickness are a little bit more than natural-looking, but not too dramatic. Will last for a decent portion of the day, but definitely not long-wearing, and will need to be freshened up after, at most, 6 hrs. *Cons: You *must* wipe the brush before applying, otherwise it will go on very clumpy. It is indeed waterproof in that it won't run but, when wet, it is very easy to smudge, and the resulting smudginess is almost impossible to get off of your skin. While waterproof, it doesn't seem to be humidity-proof. After being in highly humid/steamy conditions, I'd find that I resembled a football player. It will flake; not overwhelmingly, but still. It tends to give you Tammy-Faye lashes if you try to apply multiple coats. Maybe it was just the Basic Black was too dark a shade for my coloring, but sometimes I felt that it *looked* like I was wearing mascara.
