I have been utilizing this product for two years and I find it quite satisfactory.

It is the best drugstore eyeliner I have used. It is very high quality and pigmented and is easy to apply. I have been using my for a couple of months already and it does not dry out.

So precise, easy to make the perfect wing, does not dry out easily, and affordable! The serum is a boost! The color is also pigmented. I will say it's not very water proof though.

Beautiful liner with great control. I'm not used to using a felt tip eyeliner, but this is as good as stila at a drugstore price. The brown has good pigmentation. This never skipped or tugged on my eyelids. You can get a really nice thin line, or press a little harder for a thicker line line. I can't say anything about the last serum effect on this though, since I only use Brown eyeliner like once a week so I can't speak to that.

This is so pigmented! it does not dry out when using it on top of eyeshadows, it doesn't skip. It glides very smoothly and it doesn't look dried out at all, like when the look all matte and "cracked". My favorite so far and very long lasting.

My absolute favorite eyeliner! I'm not sure about the boosting abilities but I like how easily it glides on my eyelid and it stays on all day

I have been using this eyeliner for quite a while, I think it has one of the best aplicator point, it is like a brush pen, the point is super fine and it can create a very fine line with precision as well as thicker lines, the formula is confortable to wear, highly recommend! I will buy again.

This is the first time that I have used a liquid eye liner. I like the color (deep brown), however, I am not very skilled at applying this eye liner. It looks okay on me, but because I am older, my eyelids are no longer smooth so the eyeliner does not go on smooth. I think this would be a good eyeliner for someone younger than 55 years old. I will probably go back to eyeliner gel pencils.

This eyeliner is a favorite of mine because of the lash boosting serum. I've been using it on and off but I do think that it has an effect on my lashes. The eyeliner is easy to use and doesn't tug on my eyelids. It doesn't dry out quick but if I've had it for a while, typically I just give it a few shakes and let the product drip down to the brush tip.

After years of swearing by my Stila eyeliner, I've finally found a new (and cheaper!) holy grail liquid eyeliner pen! I keep this in black and brown and love the all day wear, especially for my eye shape.
