Quattro Pete, I am using the extenders somewhat differently than you intend. My purpose is to enable concealing components in closed door cabinets and in a closet. In those circumstances, they perform very well. But I do not normally use the remotes much further than about 10 feet away from the Next Generation receiver. So this morning, I performed a test, not quite Consumer Reports quality, but perhaps it will help you decide. My house is frame, 2200 square feet, on two floors. I went upstairs to the opposite side of the house as the downstairs television. I was able to control the TV from one floor up at a total distance of about 25 feet, which is about as far away from the TV as I could get inside a house this size. Incidentally if you choose to buy and wish to control multiple components using one extender, Parts Express sells extra transmitters and plug-ins that have three IR senders on one plug.
