Rated 5 out of 5 by from Easy to install/well designed. I guess you could say if this thing saves my life then yes its 5* all day! But I'm basing this review on design quality and installation. Its well designed and very well built allowing essy quick installation. Instructions excellent and also my question about compatibility regarding two units working together (ionisation and optical) answered very quickly and thoroughly which backed up my purchase so thanks a lot. Very good! SMOKIN!!:-)

Rated 5 out of 5 by from Easy to install smoke alarms I bought two BRK 670MBX smoke alarms to replace aged alarms. These are easy to replace - done in a matter of minutes using existing electrical connections. Good value for money. I would recommend.

Rated 4 out of 5 by from Spot on. Purchased to replace two Firex 1240C hardwired smoke alarms that had expired. Same size as old alarms and easy swap with good instructions. Battery inculuded and alarm is good for 10yrs. 4 and 3 stars due to only just being fitted but first impressions are very good.

Rated 2 out of 5 by from Flashing lights, why? Brought as a replacement for an old alarm but the mains connector is about 4 times the size and need a huge hole in the ceiling for the alarm to fit flush and as the old alarms were fixed to a joist there is a big solid bit of wood in the way. Returned and brought battery alarms. Also i accept this probably because it is written but why do we need all the flashing lights? They are more annoying than reassuring.
