I gave this product a 5 b/c it's only $1. Is it the best liquid/felt tip eyeliner out there? No, but it's pretty fantastic for the price. I love these type of eyeliners and the other one I use (which is thicker, so I like that this one is super thin), is Revlon Colorstay Liquid Eye Pen and it's $8...in terms of difference in quality between the two, I don't think the one that costs 8x's more is that much better. I read the poor reviews about it drying up...I have yet to see that happen. And even if it dries up in a few weeks, I don't mind spending $1 for another. It applies beautifully. No tugging, drying, or smudging. I don't know if it's truly waterproof as it claims but I applied it at 1pm and at midnight it still looks absolutely perfect w/o any reapplying. I will warn, because the tip is super thin, it gives a natural daytime look, not a dramatic smokey eye look. Also, I wear contact lenses and it does not irritate my eyes.
