The best eyeliner I've ever tried! Product love

I give you: Kiko Cosmetics "Definition" waterproof liquid eyeliner.
I'm what you may call an eyeliner yunkie. I've tried them all, gel, liquid, pencil, kohl and while I have affairs with some that I really like, I haven't found an eyeliner I want to settle down with... Until now.
I have quite oily skin and my eyelids are specially a problem. No matter how good the primer, base or eyeshadow I use, at some point it will crease on me. With eyeliners the problem is that they.. "run" a bit on my skin, specially if I have a long day or I laugh a lot, I will find that at some point they start going everywhere, but not this one.
Yesterday, I poped my makeup on at 8am (everyday makeup for me is a bit on the eyes and lips, concealer and not much else) and I went to work, and then out with some of my office budies to get a drink, which turned into a night out with friends. I got home about 2 something am, that's 16 S I X T E E N hours of makeup, and a hot bar in between and my eyeliner was un-budged, un-smudged, un-runned and simply perfect. To prove this miracle of makeup nature, I took a photo of my eyes (excuse the poor quality, it was late and I was tired).

As you can see, there are no blackish smudges around my eye, no extra lines, no nothing. So I can say with confidence that this, for me, is the best eyeliner ever, I completely recommend it specially to people with oily skin as mine.
