5 of 5 Wireless linked smoke detectors February 26, 2021
Reviewer: UltraClassic from Eagle River, WI United States  
This was the best price, shipping was reasonably fast. Some work to understand linking the detectors, but the internet was much better than the included directions. Would buy again right here, anytime!

5 of 5 Great business and product line February 15, 2021
Reviewer: KEC from Chambersburg, PA United States  
SmokeAlert.net is top notch.  Good product, best price and fast shipping.  What else could you ask for?  Installed 3 of the SCO500B units and 3 of the SA511N2-3ST units.  They all interconnect with each other.  Instructions from First Alert for setup are a bit unclear, but not too difficult to figure out.  I'm so glad that I found Smoke Alert.net online and would absolutely buy again from these folks.

Reviewer: Joe from TX United States  
The alarms were easy to setup and install. I hope to never actually need to use the product but they appear to work as they should during testing.

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!
