I purchased a DAC here on the 'Gon from a member in Chicago. He shipped it to me UPS, but it had some operational problems when it arrived. Whether or not shipping played a part in these, the unit was under warranty for him as original owner, so I put it back in the box and sent it to the manufacturer in California for repairs, with his name and address as the return so everything would seem kosher. The plan was for him to send it back to me once the work was done and the unit returned. All was OK until the company attempted to send it back to Chicago, again via UPS. That damn box went all around country for over three weeks, including not only a near miss in his area, but also a detour to the east coast that brought it strangely close to me in DC before veering away again. He had the manufacturer getting on UPS's case as well as himself, but with seemingly little effect as we watched its incredible peregrinations on the UPS website tracker. They seemed to try to ship back it to CA, then to miss again in IL after being redirected. The seller ultimately prevailed upon UPS to change the addressee and just try sending it straight back to me instead. Amazingly, it finally showed up here with no damage, but the unit was out of my hands for almost six weeks altogether for a repair that was performed within a week. Needless to say, UPS is not always the punctual, efficient machine of their advertisements.
