I have been using Rapidlash for a few weeks and I think my lashes are starting to grow. Also I got the mini Benefit They're Real Mascara in my Latest in Beauty advent calendar (info here). I think there are still some available. I would get it if I was you!
I don't know Benefit that well. I used to use the brand a bit when I was younger but this mascara is their only product I have used recently. It is good - very volumising and lengthening - but it stays quite wet, which isn't necessarily a bad thing. No crispy lashes but maybe a bit wetter than I like!
