## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple Replacement
*by A***R on 7 June 2019*

Replaced a 650MBX which had started to give false alarms at all hours of the day and night. Simple swap because the base-plate and wiring was already installed; Take this 660MBX out of the box, connect the battery provided, separate the unit from the base-plate it comes with (if like me you are replacing another 600 series alarm and can use the base-plate thats already in situ), flick the smoke alarm to Off in your fusebox, remove the old alarm and replace with the new one, then flick the fusebox back to On and press the button to test it.A constant green light shows it is receiving power from the mains and an intermittent red flash shows the battery backup is working. Not an electrician or tradesman so didn't want to touch the wiring, but had no problems replacing an existing 650MBX with this 660MBX.

### ⭐⭐⭐⭐⭐ Simple to fit
*by R***S on 17 January 2021*

I loved the way it fitted onto the existing mount (it was a direct replacement of a similar unit), after testing all seems to be working ok,I only hope I never need to be alerted to smoke or fire. Great value.

### ⭐⭐⭐⭐ Every house should have smoke alarm and to refresh the battery
*by T***D on 23 July 2019*

BRK 660MBX Optical Smoke Alarm it's easy to install. Mains Powered with 9 V Battery Backup and Push Fit Base . It should be in every house a smoke alarm. For the safety and time to time needs new battery otherwise it's annoying alarming in different time with no reason , but once it's new battery all good , great value for money
