This eyeliner is really easy to use, even for a liquid liner novice like me. I have to close my eyes until it dries, but then it stays on like nothing else I've ever tried. Through Southern California heat and pregnancy crying fits - this eyeliner stayed on and didn't look any different than it did when I applied it 16 hours earlier.
I have tested this liner against Almay Amazing I-Liner, and they're pretty close in the "competition".(I use Brownish Black) This Maybelline Ultra Liner seems to rub off a little bit sooner than the Almay, but on the other hand, it has a brush applicator that for me makes it easier to line with. I alternate between the two. The Almay Amazing does seem to stay put just a bit longer.
