Overall, it's not the worst d/s mascara ever, but at around $10, it's overpriced for what it can do. Apply it right and you can get a "my lashes but better" look that isn't dramatic. Otherwise, it can clump and smudge like crazy. It does, however, make your lashes feel soft and healthy. I think the problem is mostly with the brush, not the formula.
-very dark and can make your lashes look lush if you apply it right
-lashes stay soft and pliant, NOT brittle or hard at all
-seems to make my lashes look healthier
-formula stays moist and doesn't flake off
-easy to remove with just moisturizer or baby wipes
-supposedly 100% "natural" ingredients
-bulky brush that can't get at all your lashes (esp inner and outer corners)
-clumpy; you'll need a lash comb
-not waterproof -- prepare to raccoon it up!
-smudges a bit
-not very dramatic
