Olympic bar no problem. No usb C no pairing button and no 3 contact charging pins. I know how to troubleshoot problems and your mouse is broke, give me a new one or refund not a laundry list of tasks, I have no time for that. The strap broke on these after a month. Are you kidding me?! The Ohana pair took a few weeks to completely form to my feet and feel perfectly comfortable. These are a bit narrow, I have slightly wider than normal feet, but the slippers are already giving a bit. I stopped using it religiously for that reason, not sure if I?m the only one who?s had that problem. I couldnt even see the rack anymore! Because hes on deck alot, I wanted to make sure he had an appropriate pair of flip flops to wear by the pool.
