I purchased this mascara thinking it would better shape and define my lashes, but it makes a mess of the job. Since the brush is a tiny spiky ball shape, it only gives you the opportunity to work on several parts of your lashes at once (fragment of your overall lid) and then has a tendency to clump them. Almost every time I apply it, it ends up clumping my lashes and leaves a very thick overcoat appearance on the lashes. There have been several times in trying to use the brush to work out the clumps, it ends up clumping it further or putting so much on my lashes that it leaves black marks on the surrounding areas where my lashes end up touching skin. I wouldn't purchase this product again.
