BRK 660MBX Thermal Optical Smoke Alarm is rated 4.1 out of 5 by 10.
Rated 4 out of 5 by from Good replacement product Had to replace an old smoke alarm, this model was recommended as it would fit into the existing housing. However the connector had to be changed (supplied with product) which is bigger than the original so I had to use some spacers and longer screws to make it work. Product now fitted and fully functional - very pleased.

Rated 5 out of 5 by from Quick replacement I am having my hall decorated so decided to upgrade everything. These alarms are easy to fit and very effective. All the fittings were there already so didn't take very long to replace. Would definitely recommend.

Rated 1 out of 5 by from Colour Mismatch I recently purchased the BRK 660MBX and BRK 690MBX detectors together with the surface mounting pattress. Firstly the pattress is white and the detectors are a greyish / beige colour and do not match. In fact they look rather ugly. Whilst the pattress makes for ease of wiring it does make the unit look rather large. After investigation I purchased the BRK 760MBX and BRK 790MBX detectors. These have an integral mounting plate for easy connection and look much better than the 660 and 690 options. The units are about the same price so using them is a no brainer.

Rated 5 out of 5 by from Reliable Kit I have used these loads of times they never let you down, works every test keep them clean, change the battery when you should and you get your ten years out of them

Rated 5 out of 5 by from Upgraded fire detector Our household fire detector was beeping and as we changed the battery we noticed it was out of date (these things have a 10 year shelf life). We went to screwfix and brought to of these to change the whole house system. They are easy to install and far easier to replace batteries when they run down. Also the detectors are an upgrade on what we had so really worthwhile. Highly recommend.

Rated 5 out of 5 by from Great Smoke Detector Really easy to fit once you have made room in the back box. Direct repleacment for my existing detector with interlink cable. Device does not give false alarms due to oven door being opened or grill used. Would recommend this to anyone.

Rated 5 out of 5 by from BRK I purchased these smock detectors to replace my old BRK detectors which I have had for ten years. They were very easy to replace and if they are half as good as the old ones they I'll be happy.
