Eh. It's fine
Color: Black
I feel like this mascara is okay. Not fantastic, not terrible. I like a dramatic lash and this mascara doesn't give me the drama. I have been using it for about a month, so I can't really speak much to how well it helps the lashes grow. I haven't noticed any difference yet. It does flake a bit, but not a lot. Really just okay.

Doesn’t flake or smudge!
Color: Black
The is the first mascara I’ve ever used that truly stays put. I’ve tried several other brands (including many with tubing effects) that advertise smudge proof but aren’t. Worth buying!

Worked Nice
Color: Black
I really like this mascara much better than I thought I would. I'm not a fan of false lashes and since my own lashes are pretty pathetic I've tried just about every mascara out there to find one that at least attempts to make it look like I've actually got lashes. I was skeptical at first but this one actually worked quite well. It has a large brush but that did a good job at really separating and drawing them out so they looked longer and fuller. I also had less issue with overshooting it onto the eye lid/brow area so less Q tip cleanup required. I liked the mascara itself, it went on smoothly and felt nice on my lashes. It wasn't at all clumpy or cakey and was nice and light on. I also didn't have any issue with it flaking off during the day. It is a much higher price point than I typically pay for a single mascara and is not a really large tube, but I did notice I wasn't using as much of it as usual and I do like how it felt and looked on my lashes.
