Rated 4.8 out of 5 by 12 reviewers.
Rated 5 out of 5 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 5 out of 5 by Very easy to operate and convenient These alarms are very easy to operate and install anywhere. Just pop in the batteries and install on the wall or leave on a night stand. Easy to test. December 13, 2014

Rated 5 out of 5 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
