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.

    Hello. Um, thank you? Many people desire smoke alarms and carbon monoxide alarms that have a lower profile and are not as noticeable on the ceiling or wall. Let us know at 1-800-880-6788 if there are questions or issues we can help you with.

    I am replacing the exact same unit, which lasted exactly 10 years just like it was supposed to. I can confirm that this performs as advertised .

      Easy install. But I picked up box half open and dusty. As if it had been through a sand storm. Unit working properly.
