Rated 4.5 out of 5 by 148 reviewers.
Rated 5.0 out of 5.0 by Absolutely exceptional product and service! I ordered several Kidde smoke alarms and several of these carbon monoxide alarms, love them all! They look slick, are extremely easy to use, and are more compact than other products in this field. They are in use throughout several clinics and I have the utmost trust in them. I ordered them all online and had them in-hand in no time!!! Will definitely use The Home Depot online ordering system again! February 10, 2015
Rated 5.0 out of 5.0 by Pretty good value. These are the most economical CO sensors that we've ever used. Even the most expensive ones have the same expiration date to wear-out of the electrochemical gas sensing element that all of them use. Being battery operated is a mixed blessing. Yes, one must replace batteries from time to time, but that feature also allows one to mount the alarms anywhere regardless of where an AC power outlet is located, which is rarely at eye level or in hallways leading to bedrooms. We put ours in the hallway at eye level between two bedrooms and the other in basement near the furnace, water heater and gas clothes dryer about 2 months ago. No false alarms since. April 29, 2014
Rated 4.0 out of 5.0 by Good value Bought this produce as a contingency on a house sale, buyer wanted carbon monoxide alarms on upper levels. Needed two since first floor and basement were already covered by hardwired units when we renovated years ago. Saved a few bucks by buying the 2-pack. With free shipping it was a good deal considering I didn't need them THAT day. August 12, 2014
Rated 5.0 out of 5.0 by Best price for good product I was looking for 2 carbon monoxide alarms for my house. The prices are all over the map, but Home Depot had the best price AND it came in a package of 2 alarms. Great! Assembly (install batteries) was a snap and I had them on the wall in 5 minutes.

Rated 5.0 out of 5.0 by Perfect for what we needed Easy to mount and love how easy it is to replace batteries. So far, it hasn't gone off which is a good thing. November 11, 2014
Rated 5.0 out of 5.0 by Great deal You get two alarms for your home. I will get more so the whole house is covered. April 9, 2015
Rated 4.0 out of 5.0 by Peace of Mind With all the scares about carbon monoxide, I bought this unit for peace of mind to supplement my wall carbon monoxide detector. I have one in my bedroom and one by he cellar door. March 11, 2015
Rated 4.0 out of 5.0 by Work as Expected They were installed easily and have not had any issues. It was less expensive to purchase these in the two pack than individually. March 8, 2015
