I absolutely love this product! It's amazing, and makes my eyeshadow last all day long.

I did not like it. My eyeshadows crease and don't last. Disappointed.

OMG OMG OMG OMG OMG OMG This stuff works wonder!!!! Buyyy.. !!! don't bother to buy the drug store eye cream! Invest your money on the good eye primer. I swear my eyeshadow stay on place thanks to UD!!

This is my favourite primer - it makes my eyeshadow last all day. I've tried a few different ones, but nothing compares to it. It is a bit too expensive for what you get, but it's worth the buy.

Oh Urban Decay, what would I do without you? I do not know who introduced me to this product, I'm sure it was a beauty blog, but that was indeed a fateful day nearly 6 years ago. I have strayed from this primer, only to come back to it. Nothing can keep shadow on my oily lids like this primer. Not only that, but it makes the eyeshadow more vibrant. I use two primers, I always use this on my lids first, then I use a colored base depending on whatever powder eyeshadows I plan to wear (after the Urban Decay cream shadow pencils came out, I use those or the MUFE ones as colored bases.) I really like the new tube, because I found the old bottle would dry up and the product was hard to get out.

I can't believe I haven't reviewed this sooner - this is the only thing that can keep my eyeshadow on all day and night :)

This primer is awesome! It helps to keep my shadow on all day long. Never put on my eyeshadow without putting it on first. I've been using this product for a year. They changed the packaging a while ago, as I remember my first purchase was a bottle with a sponge tip applicator. Now it comes in a tube and you have to apply with your finger.

I have been using this primer for about two years now. Although it is not my top favorite, it is still ranked in my top three and I will continue to buy this (in Greed) beacause it is the best pigmented eye primer. Love it.

I've been using Two Faced Shadow Insurance for the past few years. But recently, I noticed that my shadow was creasing. I thought it might just be due to aging of my eyelids (thus deeper creases); but I decided to try Urban Decay Primer Potion to see if it might work better.

And indeed it does! No more creases.

The only thing I don't like about the product is the packaging. It works fine-- I have the squeezable tube-- but I find it unattractive. That's my problem, though. I'm not the target demographic for this brand. :) I still love the product and will repurchase.

My UD primer has lasted me about a year, and I use it daily. So while it wasn't cheap to buy it's ended up being good value. It definitely makes my eyeshadow last longer, crease less and smudge less (and I take my face off going in and out of a motorcycle helmet a handful of times each day).
I've read about people claiming it's harder to blend their eyeshadow after using this primer but I don't find that an issue at all.
You really only need a tiny little dot of this because a little goes a long way.
EDIT: just realised I have the tube version not the one with the tip on the sponge. Mine has a screw top lid and you squeeze out a tiny bit. That's much more hygienic than this one :)
