First the good: the material is soft.  The reflective material is well placed and works.  The pony tail part is down low, where I like it and isn't super large but it's made in a way that even someone with thick hair should be able to use it.

The not so good: I doesn't cover my ears completely, like the picture.  I find that I can start out with it all the way over my ears, but it will slowly start creeping up, leaving the bottoms of my ears uncovered (up to my second set of earrings - if that helps).  Of course I can pull it back down, but its just annoying, so I wear this hat on days that aren't too cold.  My hair is actually really short so i know it's not my hair thats causing it to move.  But i do like the hat enough to keep it.
Oh....in case you were wondering why someone with short hair would by a pony tail hat; i use the hole to hook the hat to a caribeaner if i need to take it off while I'm walking...one less thing to stuff into a pocket. :)
