Query: Out of Date "WIRELESS" Description

This product is caled a WIRELESS intercom. Today one would expect that such a device would work by means of radio frequency communication. Well that is not how it actually does work. In the small print you are told that it will only work if each unit is on the same electrical circuit. So it requires the house wiring to communicate between the units. This results in the units only working if they are in the same or posible adjacent rooms. In my house we have an electrical service panel with 36 circuits. This give us one chance out of 36 in being able to contact one unit from another that is randomly / remotely installed in our residence. This item should be withdrawn from sale as it is functionally useless.
