Lest anyone have doubts about OWC customer service, consider my experience with the Qx2. I had major problems with my unit, covered thoroughly in an earlier review. After two years of service, it stopped working reliably, disconnecting often and ultimately corrupting my drives (even though I was running in independent mode). No amount of tech support at OWC (and we spent many hours trying) was able to diagnose or identify the problem, so I essentially gave up on the device, considering it nothing more than a large paperweight.
Robert J., technical customer service rep at OWC, noticed my negative review and took it upon himself to contact me. After a few back-and-forth emails discussing my experiences, Robert determined that it was still under warranty and arranged to have it returned to OWC (even providing a prepaid shipping label).
OWC tested and confirmed the random disconnect problem, apparently a malfunction within the Qx2's circuitry. Within a few days, Robert and OWC returned to me--again, at no cost--my Qx2 with new innards. So far, it is working flawlessly, so I assume I was simply unlucky with the original unit.
As other reviewers have mentioned, don't trust any single device with irreplaceable files. I will continue to monitor the performance of my "new" Qx2, and trust that my problems are things of the past. Four stars for the Qx2 itself, as I'm still a bit gun shy, but six stars for Robert and OWC customer service.
