3 of 5 Battery Door latch needs upgraded April 23, 2019
Reviewer: Robert Swemba from Powhatan, VA United States  
The detector works well but the battery door latch is terrible. It broke off the second time I opened it.  Apparently other people  have had the same issue.

5 of 5 Best CO detector for the price February 13, 2017
Reviewer: Bill J from Bay City, MI United States  
Was having a problem with my older CO detector, once in awhile it would start chirping like the battery is low. This new one I bought has a battery gauge and CO % in past 24 hrs, far superior and more reliable.
