[Disclaimer: I purchased this product with my own money, and everything I'll be saying is based off my opinion, I'm not trying to push my opinions onto you, this is just to be helpful!]
To be honest, I really didn't like this product all that much, it was slightly clumpy, it was too fluid-y, I really don't feel the difference it makes, my make up did not last longer, and it costs a lot more then it is really worth, in my opinion.
So why am I reviewing it? Well, I feel like there's a lot of people who will go and purchase this product just because it is talked about a lot. There are so many other alternatives, and I just don't think this one is worth it, but I wanted to give a thorough reasoning/review, and not just say it and that's it.

[Real Life Experience]
So I wasn't going to review it until I really tried it out. I used it with my Urban Decay Naked Palette since it's what my primer potion came with, and went out for the day. Personally I don't mind creasing, I actually like it, but for something that is suppose to prevent creasing, it really didn't do that well of a job. By the time I got out of school, which was from 8-2:40pm back then, my inner and outer corners had slightly creased. The colour stay is pretty good, but I did get some movement in my shadow, and so it doesn't really hold the colour down, it just keeps the colour there. Overall, it did its job in making my shadows last, but I just feel like, if I'm going to spend money on something, I want it to be one that does more then just the basics of the job, and really holds things down.
I think this is something you can try out if say Sephora is giving out free samples, and maybe you'll have better luck with it, but I wouldn't suggest purchasing the full size until you really feel like its a good primer, because I really don't see it as "holy grail" material.
The full size version comes in a tube form and can be purchased at Sephora for $19.
For five dollars more, the Laura Mercier Eye Primer can be purchased at your local department store for only $24.
A cheaper alternative is the Elf Cosmetic's Mineral Eye Primer and it can be purchased at any Target stores, or online at eyeslipsface.com, for only $1-$3.
(Personally this one isn't that great, but if you're going to buy the Urban Decay one, you mind as well save the money and get the Elf one, because the two of them are really similar in consistency and formula.)
