Totally insane volume on my lashes! I have long but pretty thin lashes and they are unruly, but this mascara is the only one out of 100 I've tried that holds my lashes up all day! But it can sting since it can start to flake after 7, 8 hours, so if I'm going to be out for a long time, I might take another mascara that lasts longer without stinging and flaking. But this one and the green non-waterproof are my absolute two favorites, but many say it smudges a lot, but I've never experienced that.
