I've been wanting to try this for so long! It's a good one, lengthens and thickens quickly, although it can clump. Just brush through before the mascara dries with an old toothbrush and you'll be fine. It did tend to pull the curl out of my lashes, but not completely. What I really like is the brush - narrow on the end, then opens to a nice full belly and tapers back down again. This brush I'll wash and insert into another mascara (if the next brush isn't up to standard). This is worth a try, paticularly if you can get it for less than full price.
Cheers!
