First Alert - first choice ! - 09/20/2016
Reviewer: Mike Bubrick
Our firm services carbon monoxide detectors in more than 600 living units managed by a local real estate company. We have 7 years experience with all brands of CO detectors. Our first choice of CO detector is the First Alert CO400. The dependability of the unit, the power behind it 9 volts vs 2 or 3 AA 1.5 volt batteries and the secure installation method all combine to make this model a winner. So far in 2016, we have installed 340 CO-400s and the year isn't finished!
It really works! - 12/26/2015
We have this model in our 2nd floor bedroom which is right above the kitchen. One evening, we used the oven and were having some issues with it heating up. I thought we got it figured out. A little while later, the CO2 alarm went off and wouldn't shut off until we opened all the windows and got fresh air in the house. Needless to say I'm very pleased with this product and I got a new stove too!
