I've been using this one for a while now and it hasn't run out...yet.
So for those of you who don't know about essence, you should. They're pretty reasonably priced for what you get. I did a review on their concealer awhile back, so I apologize for the content, but it's pretty thorough. You can read that here.
On the packaging, it says:
eyeliner pen for a precise line
colour intensive and extra longlasting
smudge-proof
It does pretty much all of this, so nothings really wrong here. The color is dark enough, so that its not grey, thank goodness. If you accidentally rub your eye, it might rub some eyeliner off, but it doesnt smudge around (another thank goodness) and reapplying would fix that right up.
Okay, so for the tip. The tip is pretty thin and its a felt tip, which I really like. I can easily create winged liner. sorry for the blurry photo. 
Before, I was using Stila's Liquid Eyeliner pen, but that was $20. I'd say this is comparable, however, Stila's pen was thinner and the formula was waterproof, while this is not. Another product it is comparable to is the e.l.f. eyeliner pen, however, that dried out so quickly, I never got to do a review on that one!
It lasts pretty well though, and it doesnt flake off. I've worn it all day and it stays pretty well. If you feel the need to reapply though, go ahead.
It doesn't put much of a fight against water, or any liquid, so beware if you sweat. I had to put eyedrops in and it kinda disappeared... Which leads me to another thing I like about this. It comes off easily with water. I remember using the Stila one and taking it off was a pain. If I forgot to remove it before a shower, I would come out looking like a horror movie character, with eyeliner running down my face. I would also need to remove that with makeup remover after. I think that might be good though, since it implies good staying power.
Anyways, this one comes right off with my face soap and water, and it doesnt even stream down my face. When applying it, you can quickly wipe it off with a Q-Tip and everything will be okay. But if it already dried, just put some lotion on the Q-Tip. I really do love this eyeliner
