Review on 🔥 Kidde Lithium Battery Powered Smoke and Carbon Monoxide Detector - Combination Alarm with Voice Alert by Ron Coleman

I bought 5 of these alarms on the 7th June, installed mid July and today the 11th November the last one has a false alarm. The alarm went off (since the beginning of September), we called the fire brigade. These are 5 separate calls, each time defined as a false alarm. Manufacturing date is 2020, so no old stock. The fire department confirmed that the placement was correct and there was no dust or dirt to set off a false alarm. I figured I'd be content not changing the battery for 10 years, especially with a newborn (born in August) in the house. Instead, we had panic and embarrassment overnight.
