Go buy this...period. This product is awesome, better than the Shiseido cream liner, so smooth and easy to use...and the brush? AWESOME.
If you cant do a gorgeous cat liner with this then just give up lol because this is so easy to use!! I will never waste my money with the MAC cream liner after trying this.

I usually don't wear eyeliner, because it tends to smudge on my oily eyelids. I sometimes get a "stamp" on my upper eyelids from wearing eyeliner, so I tend to avoid it.
This product is not like that at all, not flaky, smooth and easy application and it will not smudge. When I went out the other night and checked my make-up in the bathroom hours later, I was expecting to see a lot of smudged eyeliner and I was very surprised to see everything looked just like right after application! Yay! I live in a very hot and humid climate by the way.
This also doesn't irritate my eyes and it sets fairly quickly.
The brush is decent, you can apply a very thin or thicker line without a problem. I applied two coats just to make it blacker, but the color is pretty black with one coat as well. I'm very happy I bought this and will buy again.

I have this in the dark black shade, and I love it. I had tried the LOreal HiP creme/gel liner in the past and I was not impressed. I've used this with the included brush which is a little thick, and as well as with a very thin eyeliner brush I bought at Sephora. This lasts through my whole work day without a smudge or fading. The price is nice as well. I like the glass jar, drug store brands rarely splurge on glass lol. I would buy again, but it may take a while before i use the whole jar.

I bought this about a year ago and ever since I kept using it religiously. Somehow I got bored of using it due to its drying formula. I don't know if it's just me, but the formula gets drier than before when I first used it. I found that it's even hard to pick it up with my brush as it dries up very fast. But, I can't deny that this eyeliner is the blackest I have encountered so far. I like the fact that it doesn't smudge on my super oily lid. whether it to be on the lid, or on the lower lashline. Except on the waterline, it won't last for the whole day. Somehow, it will get smudged anyways. What I'd do to secure the eyeliner on the lower lashline, is to put black eyeshadow over it. Here in Brunei, it costs about BND $22 = USD $17. So, in terms of price, it's definitely very costly than how it is in US. I think that would be the only reason why I should be disappointed with it. The price is definitely not up to it's standard as a drugstore brand. I can only hate it forever, since I live in Asia, and that too, in a country that is less famous. LOL.

Pros: long-lasting, doesn't smudge, natural but defined look, easy to apply, can create different thicknesses
Cons: none!

I have oily eyelids that tend to smudge so I have been using liquid eyeliner, however, I hate the harsh lines that liquid liner gives, and the fact that most liquid liners flake.

This product is amazing, it stays on my lids all day and I'm able to apply this very close to my lash line. I went to the gym with this eyeliner and it did not smudge! The brush that comes with this product can create very thin lines as well; I also like to use an angled eyeliner brush with this eyeliner. I would definitely repurchase!

This is my HG eye liner!! I have it in black, it is so smooth and easy to apply. Even the brush that comes with it is great! I've had the first one I've purchased for like 4 months? and it hasn't dried up, it still applies as great as it did when I first got it. I'm not even half way through it. :)

This is the ONLY product that actually stays on my waterline! I love this and it is such a great, rich color. My Urban Decay 24/7 liner does not have great staying power like this, and this product is sooo much cheaper. I love it and recommend it :)

Very good product. Gel glides on easily and precisely. I couldn't believe how easy it was to use. I found that the brush tickled me though while I was applying

I decided to try this product I have oily eyes nothing stays on my eyes.
This is my new favorite liner. Mac and wet and wild had great reviews but didnt work for me. I was at the chrismas tree shop and found this wasnt expensive so I gave it a try. This stays on my eyes ALL day. I will buy this again.

Bought this online in Blackest Black since my MAC was drying up....WOW...that's all I can say...WOW - IN A GOOD WAY! I even bought one for my sister who is NOT a gel liner gal because she has the REAL SHAKEY SHAKES and she loves it as well! I see no difference between this and MACS Fluidliner....oh, duh, except PRICE! :) Also comes with a decent brush to apply as well! LOOOOVE IT!
