I purchased this item new about a year ago and have been using it. I have confirmed that the USB and Bluetooth inputs are working. I have confirmed that the 4.4mm and 3.5mm jacks and the rear RCA outputs are working. There are some scuff marks on the rubber feet on the bottom. The original type A to C cable is missing, so I will include two USB cables, one from Elecom and one from a no-name brand. The LCD display is slightly off-level, but this was the case from the time of purchase and was not caused by any impact. See photo 7. To prevent any issues, please understand that I may cancel the transaction if you have a history of low ratings or no transaction history. Please feel free to contact me after your purchase.
