Fluidline in Blacktrack is the only eyeliner I've been using since 2007. No other brand or formula even compares to how easy this applies, how long it lasts and how dark it really is. Lasts even if I go swimming! I use it with my MAC 210 brush.

Blacktrack is a smooth, matte black gel eyeliner that easily lines eyelids and stays put for most of the day. It can also double as a wet base for eyeshadow to help create really smoky, dramatic looks. On the downside, Blacktrack does not stay put for me when I tightline or line my lower waterline--it migrates instantly and gives me Panda eyes. I find that Maybelline Eyestudio stays on my waterline better than Blacktrack, which terribly disappoints me, given how cheap Eyestudio is.
I am a big fan of the wing eyeliner and I love to use my Blacktrack to do it. It is very black and it dries without the glossy finish. It lasts all day and does not transfer. I've been using it for more than 1 year and the consistency has not changed, so I am very happy with it.
I apply it with my MAC 266.
