Overall I like the bag. It’s spacious enough to fit my wallet, AirPod case, water bottle, and even has a nifty clip for my keys so I don’t have to dig them out. The one flaw I’ve found is that the bag will only stick to a full surface. In other words, it won’t stick to a metal pole. The equipment at my gym is wrapped with a lot of material (EGYM equipment) so there is little exposed metal. I’ve attempted to stick the bag to the bar of the backrest, but it slides down the bar to the floor. Not ideal. The one saving grace is the strap, so I can easily hang it on a hook if/when available.
