This is my HG eyeliner, It doesn't smudge, stays on well and glides on like a dream. I have been using this for 6 years and never felt the need to try different eyeliners.

i LOVE this eyeliner. this is the first taupe/light brown eyeliner i found that doesn't drag and actually leaves a strongly pigmented line. it's a very flattering color and it's perfect for pairing with red lipstick. lasts almost all day and doesn't smudge once it's set.

Perfect medium brown. Lovely soft pencil glides onto the upper lid easily. Lovely alternative to liquid liner which no matter how hard I try always seems to look too much in the day time. Try mac's paint pot in bare study all over the lid, a slightly darker eyeshadow in the crease and line the eye with this liner for a more natural look. I like the fact this colour doesn't have strong red undertones in it like some browns do which makes my eyes look more sore than defined.

This is SUCH an amazing eyeliner! I am the kind of person that always needs to have eyeliner on, I have slightly protruding eyes and I feel that just having eyeliner on the outer lashline defines my eyes and makes me look less....I don't know.....bug-eyed. Although I switch back and forth between brown and black, depending on how natural I want my eye make-up to look, neither looks completely natural - meaning most girls would be still be able to tell I have it on. This isn't necessairly a bad thing, I just sometimes want to look entirely natural and this eyeliner does it for me! It is smooth, pigmented and matches the color of my eyelashes. If you know of the Shu Ueumera (is that how you spell it?) brow pencil in Seal this is basically the eyeliner version of it. Such a wonderful product and I'm glad I found out about it. My only qualm is that you need to sharpened and since I'm so lazy about stuff like that it is usually very dull. But still, great, great, natural product that is definitely a staple.

HG liner for sure!!! I'm so glad I discovered this little gem!! It's not too harsh for my fair skin and it's a brownish gray clolor and it compliments my blue eyes really well. I've never really been a fan of black liner because it looks so harsh on me but this is great. I'm also not very good with liner and this give me a lot of control in applying so it went on great. Staying power is amazing once it sets for a min but if you blend quickly you could smudge it out if you need of wanted to. Loving this stuff!

This quickly became my HG liner. Like people have said, there's something very neutral and unobtrusive about the color... like a dark taupe brown with a slight amount of grey in it. I'm blonde, but with this I've been able to get a very sexy, "Kardiashian" esque eye that doesn't look overdone or too dark. Highly recommended.

I am about to run out on this, I definetely should go and get one asap!. It is "just that right color" brown, that is perfect for day time look or a causal evening look. MAC says it is brown with grey undertone but I do not see grey in it. Just brown. I also think that not every color in this line is smudge free and waterproof like MAC says, but this one definetely is waterproof and extemely hard to smudge, especially after few minutes of application. When used on the waterline though it smudges. I will re purchase this one but also try other brown shades too.

After trying zillions of different shades of brown, so far I think Duck is the best brown liner I have ever tried.

A very good alternative to black and perfect for daytime. It fits my fair skin and blue eyes very well, not too harsh, but still powerful enough. No red undertones that makes me look tired and weird, this often happens with browns. Doesn't smudge! Blendable. Sometimes a little hard for me to apply on upper lashes, hard to get in between the roots of the lashes without torturing them, but generally I'm satisfied.

Probably my favorite and most used Powerpoint by MAC. I just bought another one this past weekend; but mostly because from sharpening it so much, the "lead" somehow became loose and the whole thing just slid out of the pencil. (So much for the packaging... took points off under "Packaging Quality" for that.) But despite the manufacturing defect, I love the color of Duck (taupe-gray), I love its softness (no tugging) and ease of application, and I love wearing it on my lower lashline. I love how the line lasts on me all day, and I love that it is not too harsh of a color for daytime-- or on my 45+ year-old eyes. Have repurchased and will do so again when necessary. :)

I have tried sooo many eyeliners, and they all smudge on me. Except for this one. I use it every single time I wear liner on both the upper lid and partway of the waterline. I am very fair and cannot wear black and so many liners no matter what shade they purport to be are so dark that on me they might as well be black because they show up that way anyway. Even some liners that might be lighter on other folks tend to look dark on me. Not Duck. It is as dark as I would ever want to go and practically idiot proof which I love as I am not the most talented when it comes to eyeliner. Honestly, I'd moved away from pencil liners which I didn't have much luck with to the gels, trying to find something that would not smear, but they tend to be a pain to apply sometimes and need a brush and were no better than this pencil liner. Well I'm a convert again to pencils. This is the best eyeliner. I can get a fairly fine precise line right after sharpening if I want or a more chunky line. It all works and without making me look like I should be standing on a street corner or in the circus as most darker eyeliners do. And for a huge plus, there isn't any red in it. Anything with any red at all makes my eyes look bloodshot or as if I have pinkeye. So it is an easy to use, is a true dark brown without red, stays where I put it, and defines my eyes in whatever manner I choose. Can't really ask for more in an eyeliner. I'm down to a stub of a pencil and will certainly buy again.
