The product itself is very highly pigmented and the lasting power is great. I tend to get watery eyes and this eyeliner lasted beautifully whenever this happened. What I don't love is the packaging. Too much product releases onto the built in brush and you have to wipe the excess off, which I think is such a waste. Also, the built in brush is very big and if you are not careful, you can fray the bristles by accidentally closing the cap on them. While the brush is big, it is not impossible to get a thin line, it just takes A LOT of practice and patience.
