I purchased the adapter several weeks ago and, at first, had little success in making it work at all. I sent the cable to moshi headquarters for testing and they immediately contacted me to confirm the situation. Their testing revealed that the adapter seemed to be working properly. Slightly frustrated, but impressed by the swift and courteous customer service, I awaited the return of my adapter. When I received it again, it still was not functioning in any way, shape, or form. At this point I was certain it was one of four things: my software, hardware (macbook pro 17"), the hdmi wire itself, or my television. I contacted Apple and ran some tests with them over the phone, again with no success, so I took my computer and the adapter in to the Genius Bar. Their testing also showed the adapter to be working perfectly, so my only remaining options were my hdmi cable, or the tv it self. I purchased a new hdmi cable, and brought it home.

IT WORKED!

I am very happy with my purchases all around. It is a shame I had to go through the trouble I did, but Moshi was great all the way through, and their product works perfectly just as advertised (audio included)!!!

Thanks!
