What devices are you connecting? Any possibility of using a wi-fi solution instead?
It's a Nexus 7 tablet. Right now I use a Wifi solution. I use a Logitech SqueezeBox app on the tablet that sends signals to my htpc connected to my home theater which is running Logitech SqueezeBox Server and controller. It works, but it's annoying. Seems like every time I go to use it, it's something. The htpc went to sleep even though I told it not to, or the squeezebox service isn't running, or this or that. I want to simplify it. I'd rather just stream directly from my tablet to my receiver. A Bluetooth 3.0 or 4.0 receiver would work perfect, but unfortunately it doesn't look like one's available. Oh well...was worth a shot.
Often times negative reviews are the result of either user error or simply not understanding the capability of a product. The fact that there are positive reviews makes it worth checking out especially if you have no other viable solutions. Also, often the more detailed positive reviews will identify the errors from the buyers posting negative reviews so be sure to review the positive reviews as well. The nice thing about Amazon is they'll take it back if it doesn't perform to your liking.
