Theoretically not a bad product, but I will not use it. I was new to running and started with a small Fisherman' Friend wristband where I could stash a key. As I started running more, I wanted to replace it, ideally with something that would hold an ID card or credit card. This wristband is big enough but is uncomfortably wide on my arm. If I now hold a credit card up to my arm, I can tell that this pocket would need to be almost half the length of my lower arm. For me, a pocket that magnetically clips to my waistband was a better option.
