it dident stay on very long

I usually don't go for mascaras that are dual ended, as it seems that the payout is not typically worth the extra time it takes to apply each coat, but I was pretty pleased with the results I got from this product.
First off I was surprised that the primer coat is black, as opposed to the usual white. I find that with it being black it is way easier to get the second coat on and looking dark. This mascara really does deliver thick lashes, but it is slightly lacking in the lengthening department. Not lacking enough that I wouldn't use it though... I guess you can't have it all all the time!
As for removal, I didn't have any issues and I use Avon Moisture Effective Eye Makeup remover. There was a lot of black gunk, but it did remove it all. All in all this is a not bad mascara for when you want super thick, full looking lashes.
