### ⭐⭐⭐⭐⭐ Smoke Alarm mains plus battery backup
*by K***K on 9 February 2026*

Mains powered and was easy to fit (I was replacing a very old smoke alarm). Also has a battery included which powers the alarm in case your mains power goes off. Good quality product at a good price

### ⭐⭐⭐⭐⭐ Smoke alarm
*by N***D on 3 February 2026*

Quality item and easy installation. Long life span also.

### ⭐⭐⭐⭐ Works but included batteries are dead
*by A***R on 28 September 2025*

Works as designed. Batteries included are completely dead on arrival. Your sensor will beep because the batteries are dead. Best to buy new quality batteries and do a test before connecting, the alarm should sound loud as if it is connected to power. Ordered both smoke and heat alarms, batteries dead in both.
