Kidde Carbon Monoxide Detector, Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable, 6 Pack

Works great, this is a must have if your house uses Natural gas or Propane.

I did not realize that an old furnace, even though functional, is a potential MAJOR carbon monoxide producer. Once made aware of this fact, and in an effort not to "wake up dead", I purchased these. I purposely got the battery powered ones after seeing reviews where wall outlet styles from other makers had gotten hot/smoked/caught fire. The folks who sell this unit were good enough to include the mounting hardware. It sounds like a small thing, and it is... until you finally get the time to do this chore, and the energy, and get ready to mount... and have to make a trip for hardware. The actual installation and operation was simple, well thought out, and I threw them up in 5 rooms inside of maybe half an hour. Amazon is getting better about carrying more hardware items like this, and their system is convenient, fast, and saved me a trip to the hardware store (which is becoming a nightmare nowadays). Having said all that, I was very pleased with these things and feel like the house is significantly safer.

Working for purpose intended.

Thank you, very nice.

Good deal when bought in 6-Pack. I put these in my rental properties and appreciate the instructions for location, as these work at about knee level. CO is heavier than smoke and I did not want to have the combonation CO/Smoke detectors because they need to be installed at different heights.

Works as should this brand is recommended by my local fire department

I have used these CO monitors in my house and in 3 other houses. They have worked well so far. No false alarms and the test buttons work when you push it. I have used this model for a long time. I mount them on the wall in the bedroom areas and I have some that are mounted on tabletops in different rooms including near the furnace.

For residential properties.
