I havent seen anything that compared this to the G502 on reddit (maybe Im just not looking hard enough I suppose), so I just wanted to post something here, as a totally unofficial reviewer but a consumer. 90 but without sounding so thin in the middle. The people that we went with asked if my shoes were Keens because they look so similar. All you have to do is literally stick it on the wall. I was very satisfied with the rack. The battery life is good and the noise cancellation does work. I have ordered shoes on amazon before with varying degrees of success, so I was hesitant about these. Easy to assemble - although I did turn it on its side to push the bars firmly into place in their plastic holders, when a bottom bar popped out while I was wheeling it around. This product didn’t work for me at all. I immediately noticed how comfortable the headband was way better than the Astros and Beats.
