I love it! I find that using it makes my skin very smooth and that makes the application of the makeup easier. When I first got the kit, I forgot to put the rever-upper on a few days, and those were the days that the makeup looked fake and flakey. I have oily skin, and whatever is in that bottle seems to contain it. My skin tends to flush also and the rever-upper does not make this worse at all.
My Mom just got the BE stuff on my recommendation. She has rosacea, and uses the rever-upper with no issues. She told me that she really likes the BE, that it covere the rosacea and looks more natural than what she was using before.
