Good product
30 Jul 2012
By RegencySpa

"Was recommended these for my static caravan holiday home as they don't 'go off' as soon as you start cooking. Now fitted them into my house along with Co2 FireAngel products to house and van. 10 years guarantee and peace of mind for under £15 - Great"

Smoke alarms

By Mortz

"neat little device. Amazing value!!
@"debatcher"... Normal "ionisation" smoke alarms will go off with the smallest amount of "Ionising" smoke, however cigarette smoke is "non ionising"... You need special smoke alarms to detect cigarette smoke!"

Toast Proof Smoke Detector
7 Nov 2011
By dabcatcher
, Halifax
"At last we can make toast without having to wave tea towels at the smoke detector! Why is it that the average detector will ignore quite large amount of, say, cigarette smoke or similar but will go berserk at even the thought of toast somewhere in the house?"

Well designed product
15 Sep 2012
By SaltashElectrician
, Saltash
"Easy to install. Easy to push temporary silence / test button is good feature.
On this occasion one of the two in the twin pack didn't work but manufacturer posted replacement promptly though I had to post faulty one away. Probably should have returned it to Screwfix who would doubtless have changed it for me. The difficulty was that I'd already installed one of the two for a different customer when I discovered the second one didn't work."

Faulty
26 May 2012
By MarkMcD
, NOTTINGHAM
"I purchased 2, but had to rturn 1 as Low Battery kept bleepig which was abit disapointing considering these are sold with a 10 year guarantee !!!
The replacement works fine upto now, but will confirm in 10 years time if this is still the case.
Had to buy replacement from elsewhere as Screwfix didnt have replacement stock. I am goig ff screw fix as they only carry minimum stocks , so thik i will start looking elsewhere fr future purchases as i like to visit 1 shop nd get everything fro one place and you cant do this any more at screwfix."

Good, solid product
14 Nov 2011
By AlexF
, Portsmouth
"Easy to mount, clean looking device. Reasonably priced. Happy with both the ones I bought and maintenance free for 10 years - consider replacing a battery every 2 years and it's worth paying a little extra.
Wife says it looks nice too !"

Not 10 Years!
28 Feb 2014
By Barry1970
, South West
"was plaeased for a year - no false triggerings etc. However, after 1 year we have a flat battery...on a 10 year battery product! If you have 4 of these in your house thats £60 a year to keep the alarms powered! Going back to 9v battery products.
Not happy."

Absolutely Obnoxious
8 Nov 2011
By LoversKitchen
, Kent
"Bought this alarm after reading the three excellent reviews here. Maybe mine is faulty, as it goes off if the dog farts.
It's far removed from the action (the kitchen) but if the windows are open, even a crack, it will set the thing off. Without question, the worse alarm I've ever bought. Will be returning to Screw Fix today. We've been too terrorized by it, at all hours, to even dare try a replacement."
