    This product works fine, the instructions are clear on how it should function and what the different beeps mean. My only compliant is that it is very difficult to get the backup battery into the unit. The 9V terminal attachments are in a small space in the unit.  see moreof S's review

      I own three of these for our home. Like other reviewers have stated, the battery compartment is not always good. I have one that I have absolutely no problems with, and then the other two, I have to struggle to get the battery in the compartment and close the door. It is possible, but it should NOT ...  see moreof southernvabelle's review

              My Firefighter son strongly encouraged us to get CO Monitors for our home so I purchased two of these, one for each floor of the home. The batteries slid easily into the compartment and we just plugged them in and we were "good to go." Simple set up and a good price for some essential protection for...  see moreof FireMom's review
