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.

Still a lot of cooking alarms

I bought this to replace a similar one due to it going off almost every time we baked certain foods. It unfortunately has the same false alarm rate. The "Superior" rating did nothing to make our lives easier.
