Product review (3 stars): It works!
I bought a set of these switches and outlets when Lowes carried them several years ago.  They work okay for the most part.  I find that the channel selector does not always work when connecting to a receiver.  Even when they are both on the same setting, if it is not channel 1 it doesn't always work.  But most of the time I only use one switch for one receiver.

Maybe newer versions work better?
