Probably one of the worst eyeliners I have ever used and I'm not even kidding which is the sad part. It smudges, it is not particularly black, very watery, very hard to apply and is SUPER messy. Ugh. Just hate this stuff. Wish I had the receipt!

This is the blackest eyeliner I have ever found. Unfortunately, that's where the good points end. The formula is the very opposite of waterproof, and streaks and runs at the slightest bit of moisture - tears, rain, humidity etc. The brush is tricky to master and deposits too much product, so you need to wipe the applicator on the lid of the bottle to take off the excess. I can't do precise, thin lines with it either, only thicker solid lines. If I do do flicks on the corner of my eyes, the eyeliner's formula is so easily-transferable that they won't be there a few hours later. I just can't rely on this eyeliner to not smudge and smear!

Very good liquid liner. Its extremely dark and the wand is something like a sponge tip. Its firm where I can do both thin and thick lines. I find this much easier to work with than the liners from both Lacome and Dior.

I was getting a bit sick of kohl pencils and twist-up eyeliner sticks that just weren't black enough or smooth enough for me. The only one that I hold in high regard is an Indian brand called Chambor, which makes a truly buttery, rich, budgeproof, water resistant one called Dazzle.
But I'm not skilled enough to do wings with a pencil so I went swatching for a liquid one with a sponge-tip wand.
Yes I saw the Artliner and it was too expensive. L'Oreal and the smaller brands had too-watery formulas. But Clarins had the full package. Glossy black, a sponge-tip of the perfect size and resistance (rubbery but firm), and extremely long wear without peeling (Artliner did that). Pricey, yes, but it made no compromises.
It's gorgeous. I could control the thickness of the line at my very first go, the formula stayed put where applied and dried quickly. The only con (and I'm going to be gross here) is that at the end of the day, when I'm taking off my eye make-up, the eye goop is jet black.
And yes I can now do winged tips. Though getting both eyes to match certainly takes some practice
