I needed to move this repeater my Blu-ray player to my projector connected by a cable 15 meters. This product has served its purpose perfectly. By cons, it was necessary to establish the power supply. Fortunately, the power sector was supplied with the unit (which is not always the case for all repeaters). Note, my drive is the new Sony BDP-S3100, and it seems that I need this kind of accessory that other models. The LG that I had worked without a repeater, even if the image loses quality.
