Review (3/5): It's... okay.
I ordered this about a year ago, and this product had so little impact on me that it took me this long to write a review. Anyway, the primer has next to no tint, which is good, and seemed to hold the eyeshadow to my skin fairly well. After using the primer on one lid and just putting shadow to lid on the other eye, there was a noticeable difference at the end of the day, even if it was only slight. It does the job, and that's why it gets three stars from me.
The bad, and why I docked two stars. The applicator is next to useless - it's a sponge, and doesn't hold much product at all; I had to re-dip several times to apply just a thin coat to each eye. It's also a strangely HARD sponge, so even using a light hand it ended up hurting when I tried to put product in any nook or curve around my eye. The second star is for just how little product there is - I don't wear makeup that often, maybe twice a week, three times if I'm going out on the weekend. I ended up going through the entire bottle in about a month and a half. The price isn't that bad for how little product there is, but it was still frustrating that the product didn't last at all.
If you're new to makeup or have a strict budget, then this might be good for you. However, if money is the issue, I'd recommend getting something just a little bit better to make your dollars stretch further.
