Kidde LP2 Battery Operated Carbon Monoxide Detector Alarm | Model KN-COB-B-LPM, 6-Pack, White, 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.

We bought the Kiddie product name because they are a known name. We got our 6 detectors and installed 4 of them - the 5th and the 6th detector was defective. We called kidde and they said they were over 10 years old and they would never sell that outdated product - so we had to call Amazon - they were nice enough to send us a refund for the defective ones. But beware to buy off of this seller. If he puts defective products in the package - that is not good at all!
