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.

Green Glow

Would Not Recommend

Easy to install with adapter, but at night circles on floor, walls, ceiling glows green around alarm, to bad, seemed like a nice upgrade, but going back to store today, walking down the hall was like going into a disco ! Green light on the walls, floor, ceilings, also in bedrooms, why in the world did they put an internal green light to light up around it like a space ship at night ?
