After 30 years of wearing mascara I've truly found my HG in this! I have very long yet fine, thin lashes and am more in need of volume without any annoying clumps. This does exactly that! Gives amazing volume with nary a clump and even lasts all day on my underlashes without ever a smudge. I especially adore the brush --- not too big yet not too small. Perfect size for smoothly & evenly applying the gel-like product and perfectly distributing on my lashes. Bought this back in June 09 and with daily wear still have plenty left in the tube w/o any unwanted thickening. Will repurchase without a second thought to it's somewhat exorbitant price. It's that worth it!
UPDATE (Feb. 2010): Yes, I love this mascara so much that I again shelled out the $27 for it.
