I've been using this mascara for a couple of weeks now. I really like it! It's supposed to "appear to grow" your lashes, whatever that means. All the things I tried that do grow your lashes, brows, etc. they tend to work on me, but temporarily. I didn't really buy this for the growth aspect, but it really provides a lot of length and some thickness as well. I absolutely love how black it is! The brush is really long, but still easy to use and disperses well. It's not clumping or flaking on me either- I'd recommend!
