So wow.
I've bought this eyeliner four times now, and I'm never going back to anything else.
This liner is pure black if you get it in 'Perversion', and it stays all day. I still have to set my eyes with powder or it'll stray.
WARNING: Don't use a powder that isn't translucent, it'll pick up the colour and the liner kind of turns blue...
I totally recommend this, it is worth the cost and the brush on it is very fine and easy to work with once you know what to do with it.
Happy lining ladies n' gents!

Okay, Holy Grail people. Seriously. This gives me insane precision and it's so smooth it's zero effort to apply.

I wore it on a sweaty Spring Sunday, reading on the back porch for hours, then had a sweaty romp with my fiance and still this thing didn't budge. It's just amazing.

I have it in Demolition. It's quite dark, almost black.

Please note all those complaining it's watery that the package says "Shake well before use."

I am super pleased with this.

I have the black color of this eyeliner. The brush that is included with the eyeliner is very thin and is proven to break easily. The packaging prevents one from using another brush or eyeliner applicator unless it is as small as tge origional applicator. You must shake the eyeliner before every use other wise it looks like a liquidy grey. After applying, it stays wet for a while, so you have to wait before you start your day. Overall i would not buy this again, even though i LOVE urban decay, this eyeliner was a dissipointment.

I was sadly disappointed with this product. It lasts long, and can create many eyeliner looks because of the thin brush. But the oil and the black (i guess) separated alot and i would have to shake it constantly. It also dried out after about 6 months. So now it just gives me a grey color. :c

I was disappointed with this product, it was recommended to me by friends after my previous liner was discontinued. At first I loved it, it's so easy to apply and the super thin brush makes it easy to achieve lots of looks but after using it for a while the product became really watery I'd have to shake it like mad to get a good consistency. I do like the finish of it and it's amazing staying power but I won't be repurchasing.

I like this eyeliner because it really is waterproof. It last all day without smudging, but removal is easy enough with some evoo on a cotton ball.
I like to line my waterline with pencil, but am yet to find a 'truly' waterproof pencil that does not give me raccoon eyes, so what I now do is create a barrier with this by drawing a line right under my waterline, which is simple because this eyeliner application brush is razor thin!! (also great for a cat eye) then I fill in my waterline with my pencil.
This is my new fave eye look =)
My only complaint about this eyeliner is how glossy it is. I would prefer if it was more matte. And I don't like how it flakes when removing it.

I have bought a couple of different colors of this liner. I really like the tones and the pigment in the product. It is waterproof but not rubbing proof so you just need to be careful. While I love the colors this comes on, I have also tried the black liner. To be honest, the black version of this is not as good as other liners out there. If you are getting one of those try the colorful ones... my personal favorite is Sabbath (deep blue).

I've gone through at least 8 of these liners in perversion. My HG liquid eyeliner. I use to use Revlon Color Stay liquid but the staying does not compare to UD's. Stays on FOREVER through yucky FL humidity and unpredictable rain storms. It's impenetrable. Only complaint is when it's brand new the formula is too liquidy so I have to use a separate eye liner brush to feather out the liner. I would just dab the UD eyeliner in the middle of the lid and use the separate liner brush to draw the line.

Ok, first off I was soo excited to try this out it was my first high end liquid liner. I usually use the wet n wild mega last, it works wonders. I expected this to be a matte black but it wasn't it was glossy and smelled of paint. It's super watery. You have to shake the crap out of it for it to look good. It flaked off during the day and when I would tear up it would flake off even more. I'm so disappointed with this product

Bought the shade perversion, it is the blackest black I have ever seen, did not like that is did not set matte like the product states, it was more a vinyl finish, and it flaked.
