Pros

•The 'upgraded' model seamlessly replaced an older unit with the same trim size, avoiding the need for new ceiling paint.
•Installation was simple, requiring only minor rewiring, such as removing three wire nuts.
•Simplified battery use with two AA batteries, reducing the hassle of odd leftover batteries.
•The new unit was conveniently found and purchased locally, allowing for quick replacement.
•Reviewers experienced reliable performance, with one user mentioning consistent satisfaction over a 1ear warranty period.

Cons

•Extremely loud noise poses a risk for individuals with autism and sensory sensitivities.
•Alarming noise occurred spontaneously, raising safety and health concerns, including potential seizures.
•Experienced failure in detecting carbon monoxide during a real gas leak, deemed unacceptable for safety.
•Users reported malfunctions after about 2.5 years, with persistent loud noise and unresponsive LED indicators.
•Battery replacement did not resolve malfunctions, leading to ongoing interference with daily life and peace of mind.

Bottom Line

The Kidde KN-COB-B-LPM Carbon Monoxide Alarm offers a straightforward replacement experience and efficient battery use. However, serious concerns have been raised due to its potential for loud, distressing noises and critical safety failures in detecting carbon monoxide during actual leaks. Given the mixed reviews, especially regarding safety, those with sensory sensitivities or safety concerns should consider alternative models for peace of mind.
