I have Zero and the purple one (can't remember the name off the top of my head) and I really like them. I'm getting better at lining with pencils, and these are my favorites as they go on really smoothly. I am noticing that the last couple days the liner on my lower lashline has smudged a bit by the end of the day - it could be heat (it's ridiculously hot here), and I have oily skin so I'm sure that's not helping either. I have some "liner last" that I may try over it to keep it in place for times when I know I won't be able to touch it up.
