This is indeed a great liquid eyeliner, even it's pricey it lasted for more than one year (I was using it daily). While I was using it, I had no complaint with it. The lasting power is great, it's waterproof, easy to use, had everything I needed for a liquid liner.

However, I gave it 4 lipsticks because I do believe some of the drugstore eyeliner would do the same good job as this one. For this reason I wouldn't buy this again. Unless you are really in to HE brands, then this would be a good HE item to own. It's still the best liquid eyeliner out all the HE eyeliners I used.

I love this eyeliner. I had to get used to it the first few times, but once used to it it's amazing.
It gives me a nice, black and good looking line. Great for creating a thin line as well as a thicker winged line. When opening this pen for the first time the brush is quite hard, but once the eyeliner itself comes out it softens and makes it easy to apply.

The way I use it: First start with curling my lashes(always do this as a first step, otherwise my eyeshadow and liner will smudge a tiny bit). Then I put on UD primer potion followed by some eyeshadow. Although I'm getting better at putting eyeliner on I still make a thin line with a kohl across my lid. Then I use this eyeliner and wing it out. Works great for me.

Bought this due to good reviews and I wanted a portable eyeliner (normally using MAC pot & brush which is fantastic but not portable). What a waste of money this Chanel product is. Creates a hard unflattering look (believe me, I like a sharp look to my eyeliner but this added years to my eyes) and flaked off hideously. The sort of poor performance you'd expect from a £1 eyeliner from the supermarket but in super expensive packaging. Ridiculous. Honestly, cheaper eyelners perform way better. This may have been a go-to product years ago, but these days the Maybelline and Eyekos put this expensive product to shame. continued >>

I used to be a huge fan of this eyeliner... it easy to apply, doesn't smudge and errr quite long lasting. I have repurchased this product for few times. But there are few down sides from this liner; (1) As a first time user, it irritated me because of the automatic didn't work very well, I have to keep twisted it for many times (2) after i applied it then curl my lashes, most of the liner almost disappeared so I have to reapplied it, which waste the product as well.
Although I still repurchased it for few times, I might stop buy it after I found art liner from Lancome. Or maybe not...cos its too convience to use that's all....

I've always been a bit scared when I put on liquid eyeliners. In the past when I tried these one, I didn't like it, because it was too intense, so for years I've only worn pencil lines, or eyeshadow. But today I decided to buy a liquid liner, and try it. And I must say I really like it. It's easy to apply with the brush. I've just tried it on, and I immediately could draw a nice line on my eye, it's not too dark, but perfect for my greenish blue eyes.

The best way to apply is to press once, and if too much comes out, just wipe it off on a tissue. If you don't have a steady hand you should practise on an egg. I have rather big almond cheap eyes, so maybe that's why it works so easy for me. If you have small eyes it can be tricky to apply.

Overall, an ok eyeliner. Does not smudge and stays in place the entire day. The brush though is too thick! It's hard to make the start of the line thin enough and it ends up looking like I can't apply liquid liner. The formula is kinda watery and you have to apply two layers to make the color even. The pigmentation is also not that good, kinda dark grey instead of black, this looks good when I want a natural look but simply doesn't work for a dramatic style. I don't hate it, it's just that I would like that little extra when I spend a large amount of money on a product.

I'm not very good at applying eyeliner, but this eyeliner is very easy to apply! I used to use a gel eyeliner and that was awesome, but the downside to that was that it would harden up during the winter and that made it very difficult to apply, and it didn't give me a very natural look (it was too bold). Since I bought this Chanel liquid eyeliner, I've never touched the gel eyeliner ever again (using the gel eyeliner meant I had to use a brush which is less convenient). I don't usually wear a lot of makeup, so I only apply the Chanel Stylo Yeux Waterproof eyeliner, but when I do apply full makeup, I'd draw a thin line with the stylo eyeliner followed by the liquid eyeliner on top. It's very easy to apply and it doesn't smudge nor blur. It's perfect, plus it's not expensive (in Hong Kong, at least), in fact, I was surprised at how affordable Chanel products were!! Just give the eyeliner a few twists (the sales lady suggested two twists), dab onto a tissue to ensure that you don't have too much liquid, and you're ready to apply! I would definitely buy it again and I would highly recommend it to anyone who wants to look and stay pretty all day!! =D

This automatic pen is terrible! I wouldn't recomment it to anybody, i can't belive all the positive reviews here on make up alley! it comes with a brush, that is too thick anyway to be used as an eyeliner. The packaging quality is so poore that i cant belive i paid so much for this product. The worst part is the pigmentation, like a watercolour! and it let come out too much product the can't distribute well on the brush, such a waste! thats not everything! once is on the skin it peels off! i like the antrachite colour though

Chanel seems to make blacks I can wear to work, during the day, etc and still get the clean, crisp beauty of the color without the harshness of some deeper blacks. la Ligne cake is my all-time favorite, but it can smudge and the line loses it's crispness after some hours. Gels wear too harsh for my liking (beyond tightlining). I wanted a good liquid (=crisp) without the inky weighty intensity I can often prefer for nighttime. This fits the bill. It is a sheer black, you have to go over it for a deeper tone. But it's softer, lighter and the application is very easy. You have to fuss more with this and I think I burn through this like there's no tomorrow, but for when I want something daytime black without treading into brown, this fits. I could see how this could be too sheer for some; I still tightline with my LM or Chanel cake, and then layer this over the outer 1/3 of my eyelid, above the lashline, to make a softer cat eye. If you want a richly pigmented liquid, Almay's liquid is a great deal cheaper, more heavily pigmented and comes with a felt tip brush. But that can at times wear harsh. If you prefer something of the sheerer finish you can get from a pen eyeliner (Chantecaille and Hourglass are ones similar to this in finish, pigmentation, etc) then you may like this. You have to twist this up and it does push out into gobs in the brush tip. The SA instructed me to twist up only twice. I twist once and wait, then a 2nd if need be. The tip itself is lovely, very thin and easy to get a fine point. Easier than the Hourglass and Chantecaille pens, which (though I love the formulas) can make a tad too thick of a line. (The Chante seems a tad more "black" than the other two). For something sheerer, softer, I love this one from Chanel; when I want more intensity, I stay away.

Edit: bumped down to a 3, too much fussing for more.

I am a huge fan of liquid pen liners and previously had used MAC's penultimate liner. I primarily use Chanel cosmetics so I thought I'd give the automatic liquid liner a try.
I'm disappointed - the "automatic" mechanism of the liner dispenses the product, but you have to be careful not to dispense too much. Often when applying the product it will glob over. The brush is sloppy, so you have to apply with care - but doing so results in a very transparent consistency. It lasts ok but for a product that was twice as much as my favorite, tried and true liner I expected at least the same quality if not better. Definitely wouldn't buy again - I'm willing to splurge for good quality but this was not worth it.
