    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.

    I only buy this brand. The 10 year battery matches the 10 year shelf life of product, so its a no brainer.

    Thanks for the feedback, and we appreciate your loyalty, Ken! While the alarm offers a 10-year battery life, environmental factors such as dust and debris may cause it to need to be replaced sooner. We recommend testing and cleaning it regularly to help ensure it remains working properly. We're honored to be a part of your home safety plan!

    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.
