Bought this as the other Eyeko liner was out of stock. Goes on well, easy to apply however, not so great for oily lids. Within a few hours there was no flick left on my eyes just a greyish black smudge! Think I'll stick to the Stila liquid liner.

It goes on well. Compared to Eyeko's Skinny Eyeliner, it definitely has better resistance against smudging and water. But if you have oily lids, stay away from this product. Not ten minutes after putting it on, it has travelled to the rims of my eyes. After a short nap, it's panda-eye city. You have been warned. My suggestion: Stick with Stila's Stay All Day Liquid Eyeliner. It's a bit cheaper and much more smudgeproof.

Best eyeliner I've ever used, totally waterproof, smudgeproof, basically lifeproof. I 100% recommend this.

Seriously the easiest felt tip liner I've ever used. Stays put and takes seconds to apply and perfect. Bargain!
