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.
