Tools and Hardware Reviews of Kidde KN-COSM-B Battery-Operated Combination Carbon Monoxide and Smoke Alarm with Talking AlarmCustomer Review: Great Product Summary: 5 Stars
The Kidde KN COSB B carbon monoxide and smoke alarm is a great product. This is My 2nd one. The first one I purchased outlasted the recommended life by many years. I feel safe with this alarm.
I purchased this product from Amazon because Amazon had the best price and service.

From what I can tell this seems to be a great product. It works when tested and I believe is loud enough to wake you up if needed.
Customer Review: Great Product Summary: 5 Stars
I did a lot of research before buying this alarm. I ended up buying two this model and the Kidde 442007 both are dual sensor. Oh and they were very easy to install.
Customer Review: Great Product - Poor Battery Life Summary: 3 Stars
I have had this in my house for a month now and have had to change batteries twice already. To the reviewer who speaks of 6 mos according to the product manual - Wait a little while after you buy a product to give it a review.
Customer Review: Great Value!!! Summary: 5 Stars
I originally purchased two of these 7 years ago when I moved into our new home. The two I just purchased are replacing the original two. Being a Firefighter I am very safety minded. Because these are two-in-one alarms, I think they are a super buy. About 4 years ago one of the alarms went off in the middle of the night warning of Carbon Monoxide. My charcoal grill was put back into my garage too soon and CO was building up in the house. THANKS to Kidde and this alarm system!!! Remember to replace these units every 5-7 years and replace the batteries every time the time changes...(every 6 months)
