I was so excited for this product, and the first time I used it, I was really impressed. I got flawless cat eyes with very little effort and it stayed on great. It was annoying to get it off (you have to use an oil based remover, which I HATE), but I was still sold on the product.
I don't wear heavy eyeliner every day, and I had surgery and was wearing no make up, so my Benefit liner sat untouched for about 10 days. I went to use it again and found it to be dried out. I tried pushing up more liner and then wiping the tip, but the liner was just not the same. It went on unevenly and didn't work well AT ALL. I had to completely take it off.
Maybe this product would be great if you used it daily, thus not giving it time to dry up, but it certainly did not work for me. I was so disappointed that I returned it.
