Kidde Carbon Monoxide Detector, AA Battery Powered, Portable for Travel or Home, 85 dB Alarm, LED Status Indicators, 3rd Edition, 6 Pack

Working for purpose intended.

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.

It’s very good and reliable, so far no issues. Easy to use, and keep us safe

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

If you do not have carbon monoxide detectors in your home, INSTALL THEM NOW. We have a large, newer home with two furnaces on two levels, and found out one was malfunctioning and starting to emit higher carbon monoxide levels (still within the "acceptable" range, but higher than desired) when we called our repairman. We did not have these detectors installed before, but now we have several on each level. They are easy to install, to read and use.

Thank you, very nice.

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.

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 We called kidde and they said they were over 10 years old and they would never sell that outdated product - so we had to call Amazon - they were nice enough to send us a refund for the defective ones.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!
