I was going to use it at work for the same reason as the rest of the people reviewed it - no pockets on the casino floor... I used it once and now it's sitting in a drawer somewhere in the house.
The only pocket that you can use for your phone is the one with the button, (the other one is too tight for a phone like an iPhone or similar) and that leaves you with just one more pocket that you can fit something like an ID, credit card , etc.
It's far too big than what I expected and isn't worth for just carrying a phone, rather keep it in my sock.
Didn't work for me, sorry!
