Title: Pretty much a waste of money. Wireless is a joke, not interconnected
Review: The term wirless implies that the three units are interconnected via transmission signals. They are simply individual battery operated alarms that can be destroyed within seconds by simply stepping on them. This is a toy alarm, pretty much useless in the real world. I should have paid extra for a true interconnected wireless system. Meanwhile, I will stick them on my two windows and the door. I should have returned this silly system, but I am too busy to do so right now.
