I bought one of these Apple products from Ebay on some Chinese portal. It was difficult to read what exactly I was buying, but I had a good feeling. This is a wireless router that plays music from your iTunes library (and any USB device aside). I literally plugged it in by my stereo, plugged my RCA’s into my stereo, and connected via iTunes. Easy to use, you can plug this little guy in anywhere, this device is a must for anyone who regularly listens to music produced out of iTunes. This $15 plus shipping item has really allowed me a diversity of music listening that I could have only hoped for.
