First Alert Dual-Sensor Smoke and Fire Alarm SA320AUS

Lasted 1 month not ten years – Paid an electrician to install it less than one month later battery is dead. Why reputable places like Bunnings stock this I have no idea where's the quality control. Ten year life is a joke. Don't buy this.

Rubbish product – I bought a number of these smoke alarms when I moved into a new residence in 2016. They have a shared problem of failure. First you have the cheep, cheep, cheep indicating that the battery is going flat. After installing fresh batteries it does the same thing. I have tried the remedies suggested online without solution. The best solution is to bin it and buy another brand.
