All 4 of them arrived in terrible condition. 3 of the 4 sound like they have loose screws in them.. things that are roaming around I didn’t even bother plugging them in. The power supplies are not OEM. The 4th one did not have anything roaming in it but it looked like the outside was bashed. I plugged it in and it sounds like the fan in it is hitting something. The front USB ports were all bent and bashed.This is definitely not a Microsoft authorized refurbisher. And if it is, they need to deauthorize them.
