BRK 670MBX (679) Dicon Ionisation Alarm with 9V Battery Backup is rated 4.2 out of 5 by 120.
Rated 5 out of 5 by from Easy to daisy-chain to enable full house alert I purchased 3 of these a couple of years ago and interconnected them so that if one goes off, the other2 do. Easy to wire and if purchased with the mounting kit - you have no issues with wires and stowage. Reasonable price and in my view a good product.

Rated 5 out of 5 by from Reliability I have been in my house for 20 years these smoke alarms have been in the house that length of time why would I change them apart from you should renew them from time to time so again why change if it aint broke etc...

Rated 5 out of 5 by from Easy to fit I bought three of these to replace ageing units. Quickly changed by swapping the old connector with the new one supplied and job done. (If it beeps at you make sure you have removed the battery tab on the PP3 battery, ooops!)

Rated 1 out of 5 by from Disappointing design Poorly designed product, adding hassle to installation by either requiring additional surface mounting box or ceiling junction box. Also battery was fiddly to fit and retention screw on the lid was incorrectly sized.

Rated 5 out of 5 by from BRK 670MBX Good value for money, came with 9v battery and fits in to existing plug ins

Rated 5 out of 5 by from Smoke detector Purchased this item to replace 670 type without battery backup, which this one does. Existing plug is direct fit, no need to replace with supplied plug which is different from original. Works fine, only reason for 3 stars is it hasn't been fitted that long. Original unit lasted many years in a string of 3 units so hope it will last that long
