I bought it a while ago and been using it since than and as far as good :).

I always had problems with eyeliners to stay on my waterline, they start to smudge after minutes!!!!!

With this eyeliner I don't have this problems, I might need to do some touche up, once maybe twice a day!!!!!!

I highly recommend this product to everyone that want define black eyeliner and don't need to reapply it countless times a day!!!!!! 

Very pigmented, Great lasting power. Does not smudge on my monolid eyes!

Good product but not excellent. Long lasting and waterproof, but smudges after a few hours and quite hard to remove after.

Will be searching for something else.

great for the waterline
