I love this gel eyeliner! I am very impressed with this, I have never used a gel eyeliner before and when I started using this I am sold to using gel eyeliners. I tend to stick to MAC black track since I can only pull off black eyeliner to be honest. I have used this with mutiple brushes since I am still trying to practice in applying and drawing a decent line. I have used an angled brush, a liner brush (came with it) and a lip brush! I prefer the angled brush and lip brush though. I love how it dries quickly and lasts for a long time.

I bought this product almost two years ago and I'm ALMOST 2/3 of the way done (yes, I regularly use it). I screw the lid on tightly and it still is very creamy. I don't think it's as good as it was during it's first year, but it's still really good.
It's not the blackest of black, but it's black. It's opaque. It's not 100% smudge proof, but it's very minimal smudging. You won't end up with raccoon eyes, but there MAY be the slightest bit smudging if you're an eye rubber. Setting it with powder really does the trick and then makes it smudge proof, so a little bitty step is required to make this thing perfect.

The absolute best eyeliner on the market! It stays all day and the consistancy is amazing. It's not exactly creamy but wet and it makes it super easy to work with and make a perfect wing quickly.

This product is fantastic. An absolute must have for my kit. If you find it isn't heavily pigmented enough try working the product into the back of your hand for a bit before applying (move fast or it'll dry out) then paint it onto the full lid for an amazing long lasting base for smoky eye. Buff out with a 217 brush or similar while still slightly wet. Try not to layer too much product and don't leave the lid off while you work as it can dry out quickly.

I really loved the idea of a gel liner so I decided to purchase MAC's Fluidline in Blacktrack. Having used a crayon (Maybelline's Unstoppable in Onyx) as my daily eyeliner, I was extremely disappointed with MAC's FL. I bought the eyeliner pot as well as the slanted eyeliner brush recommended by the MAC SA. I find that when you paint the eyeliner on the colour is not strong, and I have to go over the line several times with the brush before I get a solid black anywhere close to what I could get with a crayon. I'm not sure if it's my brush technique or how I apply the eyeliner, but I have been using this product for a few years now and I still find that my Maybelline Unstoppable gives much better pigment and solid colour. I will say though that MAC's FL does have supreme staying power if you use a primer and power, and after a few years the pot still hasn't dried out at all. But if you are purchasing this thinking that the gel is very heavily pigmented, be warned that it is not. I will not repurhcase and will stick with my Maybelline crayon, or perhaps try a conventional liquid liner for that strong pigment I like in an eyeliner.

Very happy with this gel eye-liner. It is very black but at times you do have to go over certain areas again to make it even more opaque. It lasts a long amount of time especially with a primer underneath.

I use this in the waterline as well as its the most long wearing product for my waterline and it doesn't irritate my eyes at all. The packaging is sleek and professional like all of MAC's permanent line and I've had this for 3+ years and it hasn't dried up which I'm impressed with.

Great gel eye liner, highly recommend!

LOOVE this gel liner!! I have oily lids and this doesnt smudge or move in at least 8 hrs! the color is great but i discovered that using a cheap liner brush the color doesnt show as much but its my brush fault. Its very blendable so when i put a cracked line ( often) i can fix it without a problem! Great product, good packaging, lasts a long time.

long this eye liner - glides on smooth. does last all day.
the only reason gave it 4 stars is because i workout during lunch time at work and it does fade a bit away. but if i use primer (urban decay) it last even thru my insanity workout dvd.

I bought 5 of these on ebay for $10(Canadian)! If you see it on ebay, it's exactly what it says it is. I usually use Maybeline stiletto (which is almost $20 here for 1), but wanted to try and gel liner, and decided to give mac a try. I heard a lot of good reviews on you-tube about it. I was both super excited and disappointed at the same time. Its seem easily transferable at first, BUT, you need a primer for this and BAM best liner ever. It goes on so creamy and smooth. It's really easy to apply and it's really pigmented, I love it. I haven't been able to put an eyeliner on my waterline for years because they just turned into a big mess because my eyes water so much. I can actually wear this on my waterline,and it lasts all day. Love love love, this eyeliner.

I've had mine for about 2 years or longer, it lasts you ages but you've got to be careful as it does dry out in the pot.
It stays on all day comes off easily too, I really want to try the blue one next:)
