I'm on the fence with this eyeliner.
I was looking for a WATERPROOF eyeliner in gel/creme form & this was suggested by an employee at Sephora.
The Good:This is truly WATERPROOF. I apply it & put a little eyeshadow over it to set it. It sticks ALL day long, even through my workout at the gym! It is the only eyeliner that stays on my lower lashline. I have hooded eyes & monolids, and I never find that weird residue in my outer corners (which MAC Fluidline constantly leaves on my eyes)
The Bad: I apply it with the Sephora angled eyeliner brush & it is a bit dry but it's not as dry as the same product in Purple (forgot the exact name of the shade). You have to make sure you close the lid right after you put some on your brush or it will dry out quickly.
NOTE: I have found that the Smashbox Waterproof shadowliner DUOs are much creamier than the single jet set pots. The duos have a little plastic lid that goes over the liner in addition to the regular cover. Maybe it helps keep the moisture in? I do find that the Duos don't stay on my lid as long though. :(
