I wanted to love this eyeliner but I'm not a fan of the brush at all. When you mess up, the eyeliner smudges everywhere. I also had issues with the eyeliner getting clumped on my eyelashes which would then get all over my hands. I've never had that problem with other liquid pens. Once the eyeliner was finally on and I was satisfied, it DID last a LONG time! I went to sleep with it on my eyes and the next day it looked as if I just put it on! I just wish it wasn't a pain to apply. Removing it is very hard as well. If you don't have a good eye makeup remover, you're going to struggle and lose some eyelashes. If you're very good at applying eyeliner I would recommend this product but I am not, and until then, I'll have to use a different type.
