in all honesty, these eyeliners are really comparable to mac's fluidlines. they last all day long, no creasing/smudging or running off. they're exceptionally pigmented and dreamfully creamy (easy to work with). i have only one objection: they're very drying. if you've got oily lids, these liners would be great for you. personally, the dryness doesn't bother me, but you might object to the crusty feel of them. you can't tell on your eye, but when you rub it with your fingers, you can feel it. they stay put, but aren't so much of a bother to clean off with makeup remover or even babywipes.
another great thing about these liners is that they come in sets of 3, and the colors vary depending upon your eye color. if you have green eyes, the colors are designed to compliment green eyes. the same for brown and blue eyes.. clever :b
i'd say yes, give them a try before splurging on something like mac's fluidline or bobbi brown's creme liners.
hope this helps x
p.s. sorry for the blurry picture! ):
