A worthwhile product
11-Jan-2013
By
, Lichfield, Staffs
"Excellent value for money,compared to some prices I have seen. This is a basic monitor but hopefully does the business if CO present. At this price it is affordable to have more than 1 around the house.The biggest decision is where to actually site the alarm given the "dos and don'ts " in the instructions, but worth having 1 in main bedroom and 1 near the boiler."

CO or CO2 detectors????
16-Dec-2011
By
, Tring
"Just to clarify the difference between a CO or a CO2 gas detector.... a CO or Carbon Monoxide gas is the type given off by the burning of fossil fuels such as coal or gas or oil. Such gases are expected to be discharged via a flue into a well ventilated area OUTSIDE of a building. It is a silent killer and too many people have died from faulty or blocked intake / extract vents (remember those holiday letting deaths....?)
CO2 or carbon dioxide is produced by combustion (car engines, volcanoes, geysers, to name but a few) and is discharged straight into the atmosphere.
A SMOKE detector "sees" the particles of smoke from a fire or an over-hot frying pan and triggers an alarm.
So we should be using SMOKE detectors (note the plural and read the suppliers guide on where you need them to work out how many you want) AND ALSO the CO carbon monoxide detectors (same point)
I use the First Alert versions and been well pleased with their quality and effectiveness (Smoke version re hot pan once and drilling dust twice)

Poor lid fixing
07-Dec-2012
By
, Blackburn
"Bought two at a very reasonable price. Very good value and one of the best on the market. However, the battery lid slips open by approximately 10mm and then refuses to stay closed. This happened on both and it would appear that the lid is designed to keep closed with a curved plastic catch latching around one of the AA batteries. Battery surfaces invariably being shiny, the catch is bound to slip off the smooth surface.
A very good buy if you are happy to live with a slightly open lid. Unfortunately my tenant isn't."

Impulse buy
14-Nov-2012
By
, Thatcham, Berks
"This was bought on impulse when stocking up with Turbo Gold screws. The price seemed reasonable and we had been meaning to get one for some time as our combi boiler is situated in the spare bedroon, (in a cupboard, venting to the outside). The very next day after purchase doing the Tesco shop we noted they were also selling a similar item but at £2 approx dearer, so a good impulse buy. Not fitted it up yet but dont envisage any problems"

"Its difficult to review this product as you only know if its any good if you have a problem!
All I can say is its a good price for this type of detector and its nice and compact.
Also comes with batteries and can be changed.

"Will have to wait and see how good it could be had to change the first one. Main gripe was the the battery access door which should close on to a plastic pin impossible to close kept bending pin. Staff in branch actually snapped the pin trying to close it easily done. Very poor idea."

Poor Build Quality
18-Apr-2012
By
, Buckinghamshire
"I hope the functionality is better than the build quality.
There is a plastic "spike" which should click into place to hold the battery cover closed; this did not line-up and almost broke when I tried to close the cover. Fortunately I noticed and made an adjustment."
