This has become my HG eyeliner. I think I'm on my 5th or 6th one by now! I love how intense the color is. It definitely does smudge if you touch it, so I avoid touching my eyes at all costs. But if left alone, it doesn't smear under my eyes or anything like that. I use this mainly in my waterline but I have also used it to line my upper lash line. I think it works great for both uses. It goes on really smooth.

I work the front desk at a salon so I deal with a lot of women every week. I've gotten tons of compliments on my eyeliner and have had some women ask me what I'm wearing and have gone out to buy their own!

My only complaint is that the smudger on the bottom of the pencil seems to come off a lot. At this point, I don't even bother putting it back on because I don't even use it.

I love any type of automatic eyeliners; I hate sharpening!! This eyeliner is really creamy and smooth; doesn't tug when you apply. I personally love brown liners but I use this to tight line. It can smudge onto lower lash line if you blink right away after tight lining, so I tend to keep my eyes open for a few seconds so liner can set. Color is very black. I love that the smudger at the end is rubber; very hygienic because you can clean it. Definitely would repurchase this and check out other shades from this line!

Edit: wouldn't repurchase. Smudges like crazy. The rubber smudger always pops off everytime I try to take off the cap.

I bought this on a fluke. This product is no fuss, easy to use, and performs as promised. An intense black eye-liner in a self-sharpening case. However, it irritates my eyes so I cannot use it.

I bought this eyeliner because I needed a black eyeliner that I could use on my waterline and tightline. Before, I had a MUF eyeliner. I like the MUF eyeliner more because if I put it on my upper lash line, it does not crease or transfer. This eyeliner is good only for the waterline and tightline. If I use it on my upper lash line, it transfers a lot. Other than that, I love it for everything else.

Disappointed. Its not long lasting and it's not dark enough. I do like the packaging though, it comes with a silicone smudger and a sharpener. Its creamy and easy to apply so this would nice if you have normal-dry skin but a no for those with oily skin

If I could I would give this a 3.5.

I have extremely oily skin and was looking for a serious long wear eyeliner. If you have normal/dry skin and your eyelids don't crease in a way that aggravates smudging I think this would probably be an excellent eyeliner. I love how black this eyeliner is, and I like the packaging and smudger tip.
It applies very nicely as well but it just smudges too much on me. If I use UD primer and wear eyeshadow wear is acceptable so I will use all this up but will not repurchase as I prefer Sephora's flashy eyeliner and am going to try Sephora's automatic wp eyeliner in hopes it's superior to this one.

I use this eyeliner on my lower lashline, and it is a very good eyeliner. The color really is carbon black, and the color glides on very easily. The only problem i have with it is the fact that, although the packaging promises "16 hours", it fades after about 3. I have to reaplly it throughout the day, and i find that if i dont aplly eyeshadow underneath my lashline, it smudges and i get raccoon eyes (and who wants that?). But overall its a great eyeliner.

This eyeliner is amazing. It goes on smoothly and is truly carbon black. I've tried tons of drugstore "black eyeliners" and they are not truly black.

I do not leave the house without black eyeliner on (bottom) and have been wearing black eyeliner for about 10 years. This is one of the best I have found (and cheap!), and have been purchasing it non-stop for the last 2 years.

I wear contacts, and certain black eyeliners will somehow get smeared onto my contacts throughout the day/night. Not from my own application! But from just the ingredients I suppose? Infalliable eyeliner does NOT do this to me - which is great, because if you have ever gotten eyeliner/mascara or any dark eye makeup on your contacts, it is UNPLEASANT, because it makes your vision blurry lol.

This was actually my first eyeliner that I bought and used often.

It is okay, goes on smooth enough.

The bad thing about it though is that despite the fact it's supposed to be "infallible", "never fail" and "16 hours"...

It's not. It actually fades in less than 16 hours. I wear this to school and I need to reapply the inner corners.

It doesn't smudge horribly though, and it's retractable so no sharpening needed and easy enough to use.

It's okay, but not the best. 3/5. I would purchase again if I couldn't find anything in this form that's better.

I ran out of my MF Aqua Eyes and desperately needed eyeliner, so I ran out and bought this (in pencil form). The liner glides really smoothly on my top lid, but when i put it on my top and bottom waterline, my eyes water like crazy all day! It's crazy: i can't even see sometimes. And stringy pieces always get stuck in the top of my eye. If you rub on it at all, it comes RIGHT off. But the staying power is good if you don't touch it. For ex: when i sleep later, i forget/too lazy to take it off, so when i wake up in the morning, it's exactly how it was last night; all i need to do is wipe the bottom. So all in all, it has amazing staying power, but it gets in your eyes and blinds you lol.
