Its not so good, in all honesty. Im not impressed by this.I was so excited to try it out then BAM buzz killed.It smells like a marker , the tip needs alot of pressure when applying to the eyelid and by adding pressure the tip of the wing goes off.Its okay for an everyday quick line ...but not when im going all dramatic on the night out ;)
Opinions vary, different strokes, different folks.

I have never been a fan of liquid liner and thought this one from Avon would be the one to transform me. For the better. No such luck. I kept coming very close to poking myself in the eyeball. Numerous times. It definitely needs a lot of precision and patience. Can't do that when one is in a hurry. Once you get a hang of it though, the eyes look more defined and an illusion of a thicker lash is created. It doesn't stay on very long though, it wipes and smudges off easily. I don't know if that is a good or a bad thing though. But, it definitely does a good job at "winging out" though creating the perfect cat eye with a flick. A great benefit. Would I buy it? Uhhh... Maybe. But, use it merely as a base liner for my usual pencil liner

I use liquid eyeliner almost everyday and winged liner is my favourite look. This eyeliner pen is easy to use and you do get a precise line. However I was rather dissatisfied with this product. The colour was dull and the eyeliner smudged at the slightest touch. It didn't last even a few hours for me.
I would use this eyeliner for a base line since it is precise but I would go over it with my usual liquid liner.

N.B. This is just my personal experience with this product.
