Customer Reviews
It works, but mostly has to be close to line of sight in my case. 
2008-09-30
I wanted to put one downstairs and then upstairs within 30 feet. I know the instructions say that building structures can cause a problem with it, but it really does not work well at all in the one case that I am using it for which is my small church. I moved around to different locations throughout the building seeing if setting off one would set off the next, but it did not work in most cases. It almost has to be line of sight. Originally, I was only going to need two, but after the line of sight problem, I had to change it to four and then added a combination smoke/Carbon Dioxide talking alarm.
Easy to set-up

The concept of these alarms are awesome and turns out they were very easy to setup. If you have a larger home where one of the detectors can't be heard by the sleeping occupants, I would recommend this type of system. I placed one in my garage to monitor if a fire occurred there. It would give my family advance warning to get out.
Great product 2008-03-17
Love that it allows devices to be connected without wiring. Let's us have (admittedly minimal) monitoring of outbuildings with ease.
