I am very pleased at the quality and new features. Hold down the game button and the preset bttuon (the one below the power button) for a while and it will hard reset and be back to normal! Error Code: 4-1"Ok, maybe that USB port is faulty too. I carry my AirPods pro in my car keychain and although it is doing ok, I have notice that the AirPods weight might make it get clumsy. 31 per pair (for 100 pairs quantity) so the markup is 188%. I love love love my shoe rack! I have been using it for a couple of years and loved it very much so I bought two more in black. The rack holds the bikes pretty good, the only small issue is that for road bikes that have skinny tires and disk brakes, it will make the bike rest in the slots on the spokes and the brake instead of the tire. The feet are height-adjustable. For someone who insists on scuffs but dont like uppers that collapse this is a home run.
