## Customer Reviews

### ⭐⭐⭐⭐⭐ Smoke alarm
*by C***H on 23 March 2025*

Good quality

### ⭐⭐⭐⭐⭐ Not difficult to install and a great for peace of mind
*by S***A on 23 March 2026*

Working well no problems at all - tested with burnt toast (not deliberately)

### ⭐⭐⭐⭐⭐ Reliable, easy to install, and economical smoke alarm
*by A***R on 11 November 2020*

The batteries on our previous smoke alarms finally fizzled, so we were very pleased to discover that exactly the same alarm was still being manufactured. This removed the need to change all the fittings as the alarm was exactly the same, and would suggest that it is a reliable and popular model. This particular alarm came as a 2 pack which also made it very economical.
