    Kidde Carbon Monoxide/Smoke Combo

    They seem to be good items. I installed quickly with no issues tested and they seemed to be functioning, but only time will tell if they last the full 10 years. There were a lot of good reviews that i looked at before purchasing. The 10 warranty, I'm not certain it exists, couldn't find on their website. You must keep receipts and have Manufacture date, date installed, which may be 2 to 10 months different. I know that first alert had a 7 year warranty and they honored it.

    Thanks for sharing your experience with us, Daniel! We’re glad to hear the installation was quick and easy and that the alarm is working properly after testing. While the unit features a 10-year battery, environmental factors like dust, debris, and humidity can impact the alarm’s performance and may lead to earlier replacement. We recommend regularly testing and cleaning your alarms to help keep them working properly. We appreciate you choosing Kidde!

    The best smoke and carbon monoxide detectors

    I used only Kidde smoke and carbon monoxide detectors in rental properties for 30 years. I had two bad experiences with the other well known brand, then switched to Kidde after seeing they're top rated in a national consumer magazine. I've never had a bad experience with Kidde detectors. The 10 year lithium battery models save money in the long run and a chore every October.

    Good Working Detectors

    They seem like a high quality smoke and carbon dioxide detector. We ordered 4 of them and they were easy to install. Tested them and seem to be in good working condition. Helps bring peace to my mind.
