As already described, is a wired infrared extension. For the price you can not go wrong. And as "Ruzz" has described, you can help with a little trick. the three IR-diodes are long enough so that the controller may disappear behind the receiver devices. The receiver section as a whole is as big as a thumb. Behind the actual receiver diode (thumbnails) of the fastening clip can be moved. For the part, for example under a board and also be attached to the rear wall of a flat screen TV using double sided tape. Very convenient. Unfortunately, as already described elsewhere, short reception range. Approximately 3.5 meters. Otherwise it'd give 5 stars.
