Not waterproof, not wateresistent. At all., 1 Aug. 2014

About me: I've been using eyeliner regularly for a good 15 years and I've tried several varieties. :)

The best thing about this eyeliner is the precision of the tip.

The worst thing is that most times when I'm applying it at the inner corner of my eye, my eye waters a little bit and I end up with a big blob of black at the inner corner of my eye. No other eyeliner I ever used has done that to me. My eyes have never watered when I apply eyeliner so I wonder whether it's something in this formula that's causing them to water. It's also just surprising to see how it disperses at the touch of a tiny amount of water.

Other than that, the liner isn't the darkest black but after a few strokes, it does become jet black. On me it lasts all day without transferring to the top of my eyelids or anything, but that said, I use eyeshadow primer and I don't have problems with my eyeliners not staying put.

Another thing worth mentioning is that setting spray...

What??, 21 Aug. 2013

I think everyone that's reviewed this product so far is crazy!When I ordered I was really looking forward in trying a new eyeliner that really stayed put for hours. But to my surprise it does NOT do what it claims!When I apply the eyeliner it doesnt always come out black, resulting in random patches and uneven applycation, yes you can achieve sharp lines but it flakes if you go over what youve done twice for a darker line!This is completely useless very dissapointed since i couldve bought 3 eyeliners at this price that actually worked.
