Best Review

Customers find the gas smoke fire alarm easy to use and install. They say it's good value for money. However, some customers report issues with the alarm frequency - it sounds for false CO warnings, beeps after 30 minutes, or gives false CO2 warnings. There are differing opinions on its functionality.AI-generated from the text of customer reviews
