Negative Positive
Title: Not what you think it is...
Review: While these devices do transmit a signal without an additional wire between the base and receiver, they are not truly infrared style "wireless" devices. The data actually transmits through your home's electrical wiring, which can be marginally effective to almost totally useless depending on your wiring. I tried using them to transmit dial up modem data, and found the system totally inadequate. Beware.
