First Alert Plug-in Electrochemical Explosive Gas and Carbon Monoxide Detector

This First Alert alarm was a replacement for one that was 6-7 years old that had reached "End" (meaning "end of life") - these devices have a finite lifespan (even with fresh batteries). The new unit was defective and showed "End" on start-up even though it had a manufacturing date of Feb. 2022 (6 months old). I called First Alert customer service and they sent me a replacement unit at no cost (and didn't ask for the defective unit to be shipped back to them). So, 5-Stars for customer service, 1-Star for poor quality control - gave them a 2-Star rating overall. Also, the First Alert customer service Rep. said that the devices have a 10-year lifespan - they must mean 10 years maximum.

We recently experienced a leak in the propane gas line leading to our house...a lightning strike arched between the line and a ground stake. It leaked for about a week before we noticed it. It left me concerned to say the least (we did have a very slight Propane odor, but could not find the source at the time). So I bought two of these gas detectors (didn't know they made such a thing...we already had a CO detector). Easy to install given the Propane is denser than air so installing at outlet level is fine.

I was given a First Alert explosive gas detector just like this which activated due to a large leak from a 5 gasoline tank leak under my house. I had no idea it would sound off for gasoline vapors. This detector is much more than a smoke or CO alarm. Without the warning I am sure the water heater would have soon ignited the gas and I would have lost my home and possibly much worse. I bought this new one for our camper. I strongly recommend this to anyone that has any gas, kerosene, LP, or other flammable chemicals in their house or associated storage areas. This detector works!

i fiund out after the purchase that this first alert carbon monoxide and gas alarm doesnt really work. i should have check the reviews first. thats what I get fir having faith in mankind.

I bought 3 for our house cause I'm on supplemental oxygen, and I can say i feel my family is safer cause im sick and sleep a lot they do everything I need it to and alert us loud so if your heavy sleeper you will hear it.

This went up very easily. It has a fairly long extension cord inside which made it easy to hang by the ceiling and plug in closer to the floor. I was pleased with this unit.

Replaced existing one that had stopped working. Apparently life span is less than I expected but wanted one that monitored both CO %26 natural gas. Not sure cost outweighs the gas alert feature, especially if life cycle is only 4-5 years.

Comes with a battery and wall mounting if you want to move the detector to a deferent spot than the part that plugs in. Testing works well. I assume it works for detection but I don't have a way to test that.

I was replacing this item with a new one as the old one had reached end of life. I was very pleased with the item during its life and thus replaced it with a new one when the old reached its end of life.

It's worth every penny for the peace of mind to have a carbon monoxide and gas alarm. It's very easy to use, I just plugged it in. The alarm is very loud when I tested it, there's no way I could miss that sound if it went off. Great investment.
