I was looking for an option for running that wouldn't be the armband I've had that keeps slipping down/causing strain on my shoulder. This is a good solution. I am glad I didn't follow the size chart exactly-if I had I would have technically been a large, but the medium fits me much better. I maybe even could have gone with a small.

Pros-I've used it a few times now, and it doesn't seem to move at all when I'm running, even at a pretty good pace. It really stays around my hips. I was worried I might be adjusting it all the time, but I'm not. I like that it has a clip attachment inside for keys.

Cons-I wish there was one pocket that had a zipper.
