If you only want to prime your lids for shadow and are not concerned about any coverage, this is the primer for you. It dries matte quickly and it does a great job of keeping your shadows on for hours. I do notice some creasing after around 4-5 hours, BUT ...I do have oily lids and I'm sure that those who don't have this problem can get more hours of creaseless wear out of it. After using this up I'm afraid I won't repurchase, I will look for a primer that stands up better against my oily lids and also provides some coverage for discoloration.

No screws needed. Snaps in place just like the factory radio. Durable. Make sure you snap off the screw holes on the top before install per the directions, they are not needed. This is a nobrainer product to buy. Id buy it again.
