I purchased this on sale as a buy one/get one free.  I had never used it but several people I knew did so I thought I'd give it a try.  It made my lashes appear to be very full and long after I separated the clumps, however, the waterproof formula was so intensely "fumy" my eyes wouldn't stop burning.  I thought it might subside as the product dried but it didn't.  It was very irritating and almost impossible to remove.  I wasn't wearing contacts at the time but I can only imagine how intolerable it would be if I had been as I am now.  If your eyes aren't sensitive at all, it'll work well for you since it's the closest thing I've seen to a permanent mascara and rock-bottom cheap!  I never used the free companion tube in the regular , non-waterproof formula after my initial bad experience, I just gave it away.
