Arrived quickly, impeccably packaged. Set up in less than 5 minutes, immediately functional. I bought this product because my TV remote is particularly painful to use to change the "source". There I all connected to the same input (BlueRay player, SFR HD decoder, HD satellite receiver) and I can pass in an instant from one to another using the mini remote control (I enjoyed his battery is included). No compatibility issues: the 3 sources give an image and impeccable sound. Think however to have or buy a good HDMI cable (and possibly HD-compatible Ethernet) for connecting to the TV. Very good product, I recommend!
