I don't know about everyone else, but I'm very picky when it comes to mascara. I find that a lot of them smudge under my eyes. I've only been using the Dejavu Fiberwig mascara (for the last 8 years or so) and for the past half year, the Dolly Wink Long Mascara (the volume one smudges).
I was happy to see that there was a new fiber mascara that is apparently very similar to both Fiberwig and Dolly Wink because it comes off with warm water.
The curling power of this mascara is mediocre, unless I do a very good job at curling with the lash curler. The application is like most other mascaras, if you're layering too much on, there's a tendency to clump, unless you comb it out. I also find this mascara takes too long to dry and when I close my eyes (while using hair spray) I can feel it sticking to the bottom lashes.
The mascara comes off with warm water, although I find that I have to massage it longer than the other fiber mascaras to take it off.
