I have a 1m extension cable for my RGB LED Strip bought to use it between strips and receiver. This receiver and power supply are no longer under the couch but behind it, which improves the reception and ventilation. The build quality is good, it is flexible and fits exactly. I additionally secured with tape to avoid the "interfaces" to slipping and dirt. The cable does what it should and is well worth the money. A luminosity loss through this cable I can not confirm.
