5 of 5 Peace of mind August 13, 2020
Reviewer: Cannons from Broadview , IL United States  
Family of first responders.  We bought these years ago and just replaced the whole system with the exact same.  They are amazing.  MAN they’re loud, but they do the job.  We’re heavy sleepers, especially the teens, but the fact that all devices talk to each other...the whole house knows what’s happening!   Even the dog runs to the back door!   Love it!

Smoke detectors were just what I was looking for.  Happy to support a smaller company here.  They arrived promptly and I got them working quickly.  Highly recommend.
