This is a great new addition to L'Oreal's already exellent line of mascaras. It is supposed to give you 30% longer lashes, and it really did! People were saying that they looked so long and asked me what sort of mascara I used. It didn't leave any clumps at all and my lashes looked smooth and dark. But although this mascara darkens nicley, it didn't volumize too much, so if you want that I would choose a different mascara, such as voluminous. Overall for dramatically long and beautiful eyelashes this is a great product.
