Customers say
Customers find the smoke detector easy to install and appreciate its functionality, with one mentioning it has worked for 8+ years. The product offers a perfect fit, including compatibility with old brackets, and customers consider it a good replacement for older models, with one noting it works well with all home alarms. While the built-in batteries with a 10-year lifespan are a positive feature, some customers report they don’t last as long as advertised. The alarm sound receives mixed feedback, with some customers reporting no false alarms while others experience frequent chirping.
