QUALITY CONTROL STINKS - DID NOT WORK!
Spent the time to research, select, purchase. Installed it and the test button failed to work. Total waste of my labor. Infer from this a lack of quality control by manufacturer. Steer clear.

This product is as advertised and was easy to replace my old hardwired carbon monoxide detectors of the same make. Just installed two of them in a few minutes today, and they have a life expectancy of ten years.
