I received this week. On fragile appearance it is a great product. Anyway you tie around the cable harness arriving on the TV and we touched. No noticeable deterioration image on a screen 40 " The switch detects the source itself when there is only one. A tip about the USB connection: There is often only one on TV. You can use the one on your TV decoder (orange for me). Even if it is in standby it delivers its 5V. Here you leave the entrance free TV to a USB key.
