I typically don't wear eyeshadow primer, but gave UD's primer a go. After a few hours, my shadow typically creases and if I wear liner, it smudges by the end of the day. After my first application of UD's Primer Potion, I was hooked!
The creamy formula moisturizes, dries easily, and the staying power lasts all day.
If you want your eye makeup to look as fresh as it did when you first applied it, I suggest trying Urban Decay's Primer Potion.
