I am very impressed by the lasting power of this eyeliner. It was able to stay on my oily lids for more than 5 hours, which is longer than a lot of my other eyeliners. Unlike other liquid eyeliners, it doesn't really smudge when it stays on my lids for too long, instead it flakes. However the flakes are barely noticeable and can be wiped away easily. It can be removed easily with warm water and rubbing. One thing I dislike about this is the applicator. The product runs down the wand and clump up or drip down if there is too much.
