When I first tried this on, I was very impressed! I normally have problems with eye liner smudging, but this stays on like paint! I realized that this product doesn't smudge, rather it flakes off (leaving no smudges behind). Problem with that is the flaked off stuff may get into your eyes! I had been lining the bottom lids and my eyes kept getting irritated. I finally figured it was the eye liner. I've now stopped lining the bottom lids (cuz I draw the lines really close to the insides of the eyelids), and only do the top lids and haven't had any issues.

Stays fresh for a good 8 hours, is waterproof as it claims. Brush is fairly easy to use. When applying eye liner, it dries fairly quickly, yet still gives you time to correct any minor mistakes with your finger tips if needed.

Would recommend this product, but deducted points because of the potential for eye liner flaking off and getting into the eyes.
