You ask, what is a remote control extender? It enables you to extend the range of your current remote control, allowing the operation of satellite receivers, VCRs, CD/DVD players, home theater receivers, cable boxes, etc., from virtually anywhere in your home. Unlike ordinary remote controls, which are effective only at close range, the Remote Extender uses RF (radio frequency) technology that operates through walls, floors, and ceilings. Just set it up and it should work with your current remote. And check out the price, only $9.99. How can you go wrong at $9.99? Not only that, you can take 2 on your first order (only $6.00 shipping) and 2 on your second order (just an additional $4.00 shipping).
