Query: Disappointed

The adapters make this product non-functional for me. With some wiggling I could get sound to flow through the device, but cables were too loose to maintain the signal if it were bumped or even after switching to another input. If the inputs were to simply take the full size optical plug, I suspect this device would work fine (in fact several other options seem to do just that and I'll probably order one of those, next).The adapters don't snap very tight, either. They pop off of the cables easily and made it very hard to debug the problem. Just disappointing!
