Great Experience March 19, 2015
Reviewer: Anonymous Person from DAVIDSONVILLE, MD United States  
Order was shipped same day, and I received it within two days.  Units were easy to install as I was swapping out previous models of First Alert that were only Ionization.

Seamless Execution March 17, 2015
Reviewer: John Flynn from Smyrna, GA United States  
Had to replace 1/2 dozen 14 year old smoke detectors and wanted the Consumer Reports highest rated dual detection models. Was determined t find them at a big box store but neither HD or Lowes wanted to make it easy to find or order these. Saw the listing for Smoke Alert whenI searched for the units and was attracted to the fact that it's run by former firefighters.
VERY pleased with my order and the whole experIence. Got immediate follow up response to my order and several status follow ups to keep me in the loop. Order shipped next day as promised and showed up on time. Everything was exactly as ordered and met my expectations 100%.
Have notified all neighbors in my 15 year old neighborhood that they need to replace expired detectors and strongly suggested they order from Smoke Alert. Will definitely order again when I finish my basement later this year.

Best Price Fast Shipping March 14, 2015
Reviewer: MARK HENDRICKS from BRENTWOOD, TN United States  
I'd buy from these guys again for sure.
Sad there was no adapter for my old wiring so I'll have to wire in the new pigtails.
