Rated 5 out of 5 Best Alarm I have been using these alarms ever since the Fire Brigade gave me some for free when doing a fire check of my house. They last 10 years and so are good value as you never replace the battery. Definitely recommend the alarm and the price at ScrewFix. 15 Aug 2014
Rated 4 out of 5 by Lasts 4 years not 10 Low battery warning after 4 years. At the time of writing (2014) it says to replace the unit by 2020. Other than that, it's a good unit and I will replace it with the same make and model. 30 Jul 2014
Rated 1 out of 5 by Do not buy! I bought two of these smoke detectors. Initially they were fantastic, no false alarms and unobtrusive. We came back from holiday last summer (after a week of hot, humid thundary weather) a year after fitment and overnight both alarms were giving a low battery warning. I contacted Fire Angel and replacements were sent. This week has seen similar weather conditions (a year after replacement). I noticed a scratching noise and finally worked out it was the smoke detector. No low battery warning this time the alarm was just completely dead. I googled this time and found loads of reviews giving similar experiences to mine. Not trying for yet another replacement because you need to be able to trust a smoke alarm so going to try the Kidde 10 year optical alarm (unfortunately not sold by screwfix) as it is on a fire service recomended list and I have been really impressed by their carbon monoxide detector. 19 Jul 2014
Rated 5 out of 5 by OAP I fitted 2 for a 90 year old man as he or his family dont have to worry about the battrie going flat. 20 Jun 2014
