I heard raves about this one, as it's pretty much to the famous Bobbi Brown one. So I tried.

Paid around 15 bucks for it and I have to say, I'm quite happy with the result.
Pro:
--For my extremely smudge-vulnerable eyes, it does not smudge badly;
--Amazingly, it does not overdy crazily, unlike other anti-smudge thing I use --Kiss Me;
--Not that difficult to take it off, do use makeup remover though;
--For a non-eyeliner person, the brush is neither too hard to hurt my eyes, nor too soft to apply on. It is not that difficult to apply it at all, unlike some liquid or pencil eyeliners I'd used;
Cons:
--Do twist the bottle tight or it will dry over time;
--Do clean your brush weekly or it will be comtaminated, and do not share brush with anyone, and try to cover it when not using it;
--Choose gentil eye makeup remover, the ones with oil rather than the ones with alcohol, still require some effort to take it off so hold your hand steady and don't apply it while driving because one false stroke will require some un-dos;
But it's worthy every penny I paid, it is pretty close to BB one with half of the price, and it will give astonishing results, esp for night parties if you use it wisely.

cheers.

i have the oilest eyelids. ive tried mac fluidline and bobbi brown's gel liner.. and they smudge. yes, i know.. i almost gave up on gel liners.. till i saw kate at watsons in singapore and read the reviews here and i gave it a try. it was unbelievable easy to use and did not smudge at all! it gave a really nice colour!! its my HG now! :D im so glad i bought it! i tried brown colour as well, it was super good. the staying power was just as good! however, the price of it was rather higher than other drugstore brands.. but im not complaining as long as i am able to find a nice decent liner to line my eyes without smudging! yay!

I own quite a few Japanese drugstore gel eyeliner, aside from my Cosmetex Roland one, this has the most tendency to either do a David Copperfield or migrate to where the eyeline meets my eyelid. It still does the same thing though, just not as conspiciously when I use UDPP to try and make it stay. On top of that, I bought it for about 6 month now, I hardly ever open it, and keeps it standing on its head for the sake of it not drying out... it's still drying out and becoming clumpy... I only ever use it now to practice my eyelines... but before it gets all dry and clumpy, it does have a rather smooth texture and it's quite pigmented. I have to say, the brush it comes with is amazing, its just as good as my BB ultra fine liner brush, no matter how often and roughly I wash it, it doesn't flay or anything! So I switch between these 2. Took 1 lippie off for the staying power, 1 more off for drying out too fast :(

This is the absolute HG in gel eyeliners. It's cheap, it comes with a brush, and all for SGD 25!!! I bought this in black 2 days ago, and I am LOVING this gel eyeliner like I have never loved any other gel eyeliner. It stays on regardless of how much I tear (from yawning, which I do a lot of haha) or how much I sweat! Today it's lasted me 10h and counting without touchup or smudging!! And mind you, I live in a country that's practically sitting on the equator (read: REALLY hot and humid!).
Single-lidded Asians, this product was MADE for you. Whereas MAC and Bobbi Brown both come off on the bottom part of the top lid where it folds over and out of sight, this one STAYS ON. It would probably stay on in a typhoon.
The brush that it comes with is ten times better than my MAC and Bobbi Brown eyeliner brushes (yes even the award winning Ultra Fine one), and if I ever lost the brush, I would buy this product again JUST for it. It's the BEST.
Previous brands of gel eyeliner tried: MAC Fluidline, Bobbi Brown.
P.S.: I note that some users have commented that the silver and gold versions of this aren't good, but the saleslady explained to me that those colours are not meant to be eyeliners per se - it's for you to mix with your black or brown eyeliners before application as you please, or to go over a line already drawn for a gold/silver shimmery highlight. :)

By the sounds of it, most people here are reviewing black and brown (dark shades at least), I haven't tried those so can't comment here. This is a review for gold (GD-1).

A friend let me this to try so I can foray into the world of gel eyeliner... hmmm, not a good first impression! Very glittery and I can't get a smooth line out of it. We have agreed that it is the problem with the formula - it really is glitter mania, you're probably better to use this as eyeshadow, albeit a rather bling one, I'm a bit old for it... (I have since tried other gels and I think this is just a bad one off...)

I have around 5 japan drugstore gel liner, and I can say kate is just average. It smudges a little for the day, best if you intended for smoky eyes. The gel is very easy to dry, when it is dry, it becomes harder to use. The texture is matte, useful for drawing a thicker line. Overall very average.

I LOVE THIS PRODUCT!

I am still a newbie with eyeliner. Pencil eyeliner works well, but I haven't really found a creamy one. Liquid eyeliner just makes my eye twitch when I apply. I tried Stila Smudge Pot, but it was difficult to apply. I found it troublesome and difficult to apply eyeliner, hence wasn't inclined to use any liner for that matter.

That is until I tried Kate Gel Liner. Bought it on impulse in Japan, based on the rave reviews on how easy it was easy to apply. And I wasn't disappointed! My first application was so easy and it took me just 5 seconds to apply a perfect line! No joke! I was amazed!

The brush which came with the Liner was perfect too. Perviously I tried with an angled eyeliner brush and the effect wasn't too impressive, but once I tried with this brush, I was sold. The brush makes a big difference to the ease of application! Like one of the other viewers, I would consider buying the product just for the brush alone. Though I love the product too. Heh.

Bottom Line, totally worth every single buck spent on it! :)

I have used several mainstream gel eyeliners: Bobby Brown, Stila, Mac, L'Oreal (HiP) and this gives me the best POP. I was satisfied with the Mac Fluidline in Blacktrack for a while but I noticed in pictures that it showed up pretty light. I searched for a more pigmented black gel eyeliner and I bought it from eBay for around $15. I LOVE this eyeliner! I have black hair so this definitely makes my eyes pop. The brush that comes with it is okay but I use my 208 brush with it. LOVES it.

I got this in the color BR-1, a dark brown shade with non-chunky gold glitter and it is gorgeous. As a powder gel liner, it is only semi-water proof. It cannot withstand water and rubbing at the same time and causes it to smear.
I gave this a 3 because the brush was great - not too flimsy or too stiff, comes with a cap too so you can just throw it into your makeup bag. The liner was slightly hardly than the BB gel liner and much hardly than the mac fluidlines. While this is easy to apply, I prefer to wet my brush with some water because it makes it creamier.

My problem with this prevents me from using this ever again. First of all, I am a contact lens wearer with fairly sensitive eyes. I used this liner to tightline my upper lashline and about half an hr later, i felt like something was irritating my eyes. I took my contacts off to find that the liner had migrated ONTO my contacts! There were brown smudges on the contacts and the liner made my eyes itchy, red and watery which made the liner fade.

So basically, this liner got onto my contacts, made them itch and water and faded.
Will not repurchase.
