What Customers Are Saying

The smoke detector is a reliable and quality product that provides good value. It features a 10-year battery life, eliminating the need for frequent battery changes. The detector is easy to install, with a simple plug-and-play setup and included adapters for replacing old detectors. Some reviewers noted the ability to interconnect the detector with other alarms in the home. While a few customers experienced issues with the battery life not lasting the full 10 years, the overall consensus is that this is a good smoke detector.

I order 4 Smoke Alarms and 2 Combination Smoke Alarm and Carbon Monoxide Detectors at 1:42 PM and it was ready for pickup at 2:01 pm. I got to Lowe's and checked in and they were at my car in under 2 minutes. Can't ask for anything more. Thank you Lowe's and your workers. Jim S.

Replacement Smoke / co2 detector

Got these to replace my old ones that were beeping.. Easy plug and play, but the outer bracket was different.. The only thing interesting was that you cannot open the 9v battery compartment like the old ones.

Told they can’t sell them

Would Not Recommend

I had bought four of these and I needed to return two of them. When I returned them, I was asked when I got them and they shouldn’t have sold them to me. I had picked them up less than a week earlier at a different Lowe’s.

Great Replacement!!

Easy to replace existing smoke detector. Love that it is supposed to last 10 years without needing to change the battery.
