This is by far the best mascara i have used and i have tried many! It leaves you with dark, clump-fee, long lashes. Best of all is that it is waterproof so it doesn't smudge.
The only problems i have experienced is that it does not last long. There does not appear to be much mascara in the tube. Since it is waterproof it is also a mission to take off. It comes off quite nicely with my Clinique Waterproof make-up Remover.
