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.

Price has come down in three years

Bought this one to replace an existing one that lasted only three years instead of ten. So don’t know how to rate this particular copy, but sure unhappy about the previous one!

Exact replacement

Would Recommend

I bought this smoke detector to replace the one that stop working after 10 years. It’s easy the exact same type and very easy to install just snap on the wires together. Highly recommend.

So far, so good

Would Recommend

So far, so good. The connectors were compatible with the previous smoke detector wiring. Electricity did not need to be turned off. So far no chirping or false alarms. I liked that I was able to get a well-known brand at a good price.
