I saw these on creative's site a year ago but they weren't available. Then last month they were on this Amazon storefront for less than half price. I got two. One streams my internet/computer generated music across the house to the big stereo in the family room. Works great. No network conflicts no strange noises or popping.The second I used to transmit the rear sound of a 7.1 surround sound system for the TV. Same deal, works great, no wires to the back side of the room. Why they stopped making them I don't know.Now I am looking for extra receivers.
