My favorite e/s is the Revlon Wet/Dry line, but as the colors I like best seem to be disappearing, I decided to experiment with other e/s lines out there.
Avon's e/s is a very nice shadow that isn't overly pigmented. It's very easy to control how dark you want it as a result, which is nice if you aren't a fan of clown eyes. =) On my eyes, it wears very well, and my skin is on the oily side. I have seen no problems with creasing, so I'm very happy with it. So far, I have the neutral medium, neutral light, and cancun duos, which I think are all great, especially for the price.
