I used this as my first ligit eyeshadow primer and now I will never be able to live without it. This is an amazing eyeshadow primer. I'm not sure it's the best one, but if you get this primer for the 10 sale price it's beyond perfect. This stuff keeps your eyeshadow in place, and actually enhaces the color payout of the shadow. If you're on the fence, this primer meets it's review stars.
