When you lose or break a remote control the equipment is almost useless with a fraction of its functionality available. Unfortunately most companies charge an arm and a leg for a replacement remote such that you either have to search online for a used remote or end up scrapping the equipment and buy a new piece. If you have the Monoprice. 4x2 True Matrix HDMI Switch (PID 5312). you don't have that worry. Just get this replacement remote control for your Matrix and continue using it for years to come!
