Great product at a good price July 16, 2018
Reviewer: Dwight Scoles from Apple Valley, MN United States  
The fact that these alarms talk to each other and have locations is a real plus since we have 10 locations in our house.

Seems to be fine, setup took a few minutes June 1, 2018
Reviewer: Bubba from clearwater, FL United States  
They setup easily, and seem to work on the bench, but I tested with real smoke from a burning paper, (blown out), and it seemed to take awhile for the alarm to go off!  I guess I have to wait for a real fire to see if they will work right!  I had the smoke go right into all the vents on the detector!

Difficult process April 3, 2018
Reviewer: Andrew Petro from Beaver, PA United States  
Interconnecting units is difficult.  Service rep was very knowledgable but even after multiple attempts we could not link the units.  I had to go to a remote location, without interfering electronics to connect the units. Still not sure if all are connected.
