Honestly in my opinion this is the absolute best eyeliner everr. It's super dark, truly waterproof, and easy to apply for me at least, I'm no liquid eyeliner novice though. So for me, It's worth the money. it's a splurge for me, but I can buy cheap blush, powder, primer and lip color, but as far as my eyeliner. I want THE BEST. (By best, i mean highly pigmented and truly waterpoof for my oily a**) And I've tried googling and searching for one similar but none cut the mustard. Now, I've bought it twice already and it usually lasts 8 months, give or take a couple.
Warning: yes, As it ages it gets thick and clumpy..but still usable... still I would rather use it then let it go to waste and it still lasts literally all day. Bottom line, I love this eyeliner. And each time I try to find another one BETTER I never can. So go ahead and try it!
