At first I was really excited about this product since there was so much hype around it, but when I bought it for myself I found it a little less than fantastic. Personally, the application of the product was mostly patchy and it would run out of product VERY FAST. In the liner\’s defence, once it was applied (and under the condition that it was working), it was somewhat easy to make fine, sharp lines for winged eyeliner which lasted most of the day without smudging. But overall, it ran out of product super quickly and since IT IS pretty pricey for eyeliner, it\’s just not worth 25$.
