Gander: Still working well 7 years later

United States on Nov 27, 2023

MG: So far so good I used command strips to hang these on the fireplace and basement

Alice F: I was very happy to find out it is still the same size as the old one we had to replace. No drilling new holes! After putting the battery in and pressing the test button, I was wondering why it kept beeping periodically. Turns out the battery it came with was dead.

Mary J. F.: I recently had furnace repair done on a 20 year old furnace. The tech asked if I had a CO detector. I did in the furnace room. He told me they last only about 5 years, so I ordered a new one. He recommended dating the back of the unit and replacing again in 5 years, which I plan to do. I put in the batteries and tried the test button a couple of times. Seems to be working great.

Charles logsdon: I own a motor home that has a carbon monoxide detector installed near the floor at the gas stove and range. I have now had two failures of hard wired CO detectors (original and replacement), and the cost was about three times higher than the First Alert CO detector two pack. I now have a 9V battery powered CO detector in the same location in the kitchen, and one on the wall in the bedroom. I feel good knowing if I ever have a CO issue in my motor home, I should get adequate early warning, so we can get outside to fresh air before there will be a health concern. The First Alert CO detector was easy to install.
