I bought this yesterday and am pretty impressed - set up on my ipad / iphone was painless and works well with music streaming (although didn't work for all sounds e.g. I couldn't get it to work with Skype for some reason) but the main reason I bought it was to connect my new MacBook to the same high quality speakers I run on my desktop Windows PC without trailing wires. Set up was initially an issue as I already have several Bluetooth devices connected to the Mac (e.g. a keyboard, magic mouse and trackpad) and whilst the mac found the Logitech quickly enough, it advised I should disconnect one of the other devices to ensure seamless playback. I initially refused and the pairing failed and gave an error. Reconnecting, I accepted and it all worked. I was also then able to reconnect the other device and that worked too. Other than that, music quality seemed absolutely fine at close distances (<3m), haven't tried it through walls or longer distances yet. A very useful little gadget for me, docking 1 star for the set up issues but they could be Mac related rather than the device itself.
