unfortunately still not the one for me :( my eyelids still eat up most of the product. in terms of being waterproof - i can wipe it out easily with damp tissue too..

I've tried other liquid liners even Japanese ones and I keep going back to this one. Only complaint is that it runs out in a month or two for me lol

The pen tip is very stiff which makes it easier to control and to wing my eyeliner.  It doesn't dry completely matte, there's still a bit of sheen, but it's ok.  It is pretty long-lasting, but you MUST prime your lids!  I've used it without priming my lids first, and it smudged within a couple of hours.  But once I primed my lids with eye shadow primer and a bit of powder, it lasted all night.  So overall I'd say this product lives up to the hype, but with some caveats.  

the eyeliner does it's job, the brush is precise, but it dries out quickly 

I really enjoy this eyeliner. It doesn't smudge or transfer onto my lid. It's a beautiful rich dark brown color. Wore it all day without any problems. Will definitely repurchase again.
