I have always been on the positive side of the fence with Diorshow, I dont think it lives up to its claims; however, its definitely near the top of my all time favs (Armani Eyes to Kill takes the cake). After a hefty post-Christmas Sephora purchase, on the way out I noticed Extase on one of their displays as a Beauty Insider only purchase, and I knew I wouldn't be able to leave without buying it. The first time I used it, clumpy, and very thick.The brush is different (like a snowman) but seemingly easy to apply. I think the trick with this mascara is to not judge it by its first uses, because now after the 5th or 6th time - its perfect. Once the initial mascara that the brush has been sitting in for months is gone, its fantastic. Gives me nice fanned out lashes with great length & volume, and as one reviewer said, its fantastic layered over another mascara. My routine is Lancome Oscillation Power Boost + GA Eyes to Kill + Diorshow Extase and boom - Lashes!
EDIT: I'm not liking this so much anymore, seemed to work great a couple times, and now its back to clumpy, wet lashes that are somewhat scary. Won't repurchase anymore.
