So, I was in the market for a dark black eyeliner that didn't rub off right away, something that would last all day long and that was blacker than black....well FINALLY I found it...this liner is AWESOME!!! It is the best liner I have tried and I have no complaints. I have been using it for a month and it doesn't smear on me, it lasts all day long and I love how I can at the end of the day just wipe it off with a makeup remover wipe and it's gone. It is a bit pricey considering it's just a black pencil, but it is worth it. Give it a try! I am so happy that this liner lived up to the hype, I couldn't wait to buy it and try it and I am so happy that I LOVE it!!! Will definitely repurchase.

This eyeliner, despite it's hype, sucks. I was very disappointed with this product because
1. it transfers to the bottom of my eyes
2. it doesn't last as long even if a primer
3. it smudges a lot and then stays at that smudged position (if that even makes sense).
I have monolids so I really thought this eyeliner would hold up, but it didn't. It smudges and transfers especially when I tightline my upper lash line. It immediately smudges to the bottom of my eye, making me look like a raccoon!
Very disappointed and a waste of money really... I really wanted to like it and I tried this eyeliner several times before writing this review.

Chiming in with everyone else: super pigmented, creamy, the blackest black I have come across.
The smudging isn't the deal-breaker for me. No, the problem is my contact lenses. Sigh.
This pencil RUINED a brand new pair of lenses for me. It may not matter at all to people who wear daily disposable contacts, but I wear toric lenses (for astigmatism) and my lenses are mad pricey--in the $100 range--and I only get one pair per month. I tried every c/l solution I could, even the hydrogen peroxide based one that fizzes--NOTHING could remove the UD.
So, yeah, the staying power is great....just not where it SHOULD be.

I've already bought this eyeliner twice. I LOVE it. I first tried it when I was looking for a black liner and a makeup guru friend recommended it. I was kind of turned off at first by the expensive price but man am I glad I tried it! It glides on like nothing else. Seriously. It's soo pigmented and creamy it's truly the blackest black you can get. I love this stuff, but I use it up really fast. My only problem with this eye liner is that it can tend to smudge. Especially on the bottom of your eye and if you put it in your water line. It smudges through out the day or if you touch your eyes at all so you need to bring a wet makeup wipe to clean it off sometimes. I still love this stuff though because there is nothing like it.

This is the richest black that I've ever come across. It applies effortlessly and opaque with the first swipe. Sadly, after two hours of wear this smudges with no mercy. I literally had raccoon eyes. I don't wear contacts, and I used this product on my waterline.

Okay so I love the 24/7 liners and I don't have any problem with the other ones that I have, but for some reason perversion just doesn't work on me.
Yes it is a deep rich black, and it glides on just like the other 24/7 liners, BUT it smudges like crazy (even when I don't put it on the waterline) within 2 hours, giving me super dark raccoon eyes (thanks to the *blackness* of the pencil). I had really high expectations for it and am so disappointed.

I was so exited to get this after reading all the reviews about it being the blackest black that ever was black... And it didn't quite live up to my expectations. It is the second UD 24/7 liner I've tried (the other being Ransom), and both of them have given me mixed results. It is super, ultra excessively black, and very soft and smooth, but it is easy to end up with too much on, so it smudges more than you want before it sets. After it sets it hasn't smudged on me. When I've worn it on my waterline I've found it mostly lasts, I'm still wearing some 8+ hours after putting it on, it's disappeared near my tear duct but 75% is still holding on and my eyes still look lined. BUT on my waterline it really irritates my eyes sometimes, which other liners don't do, so I don't reach for it as often as I thought I would. I also have found it annoying to sharpen, the colour is so soft it breaks off before you can get it really sharp (even after I've frozen it), and the wooden pencil is vey difficult to sharpen (and it sharpens into pointy bits of wood near the colour).

This is one of, if not THE, blackest pencil liner I own. It is also the softest, but it is too soft. It transfers all over and smudges. It is not a great pencil to own if your eyes are sensitive. Since it is so soft and smudges and transfers so easily, it got in my eyes and burned. It made my eyes red and watery. I will not be repurchasing.

If you have sensitive eyes or wear contact lenses then stay away from Perversion! I am a huge fan of the 24/7 liner pencils but this one transferred into my eyes and burned like crazy! I used it once and experienced extreme irritation. I returned it the next day and got a full refund. After all of the hype, I was extremely disappointed in Perversion.

The best black eyeliner ever.
This eyeliner, true to its name, will stay on all day. In fact, the only complaint I have is that it's often hard to remove at the end of the day.

The formula is creamy, and appears almost liquid-like when it's on your lids. It's easily smudged, perfect for a smokey eye.
