    Like many, having a gas boiler always can emit nasty gases at some point, best to have an alarm like this to save you and your family should something go wrong

    Golden Review Award: 3 From Our UsersSeems good quality. Note that the instruction manual says that when you test the alarm there are 9 beeps in total and that they are all “loud”. I noticed that the first four beeps of my alarm were low volume and not loud. Customer service were helpful and confirmed that there is nothing wrong with my alarm and that their instruction manual is incorrect. Hopefully this helps someone

    I have this in my little ones room as the boiler is in there, works well so far as I test it once a week and no problems with it. had for about 6 months now.

    Product good and as described. Delivery on the day as promised but just left by front door with a brief knock on the front door, no waiting for an answer, though we were in. That’s Amazon. Good job it wasn’t raining as the package was just paper.

    Looks similar to the one it replaces, but now only requires two AA batteries, not three. And they come with it. And they are Duracell branded, not some cheap rubbish ones. Should last 10 years like the last one did.

    Golden Review Award: 3 From Our UsersThis item arrived well packaged and in the allotted delivery time. It is really easy to install. I didn’t use the wall fixings, but it just sits on the top of my cupboard in the lounge. I didn’t realise that it had to be placed high up; I hadn’t done this with my last monitor. Also be aware that these monitors have a battery life; so don’t be caught out, you will have to replace after so many years (it tells you on the monitor how long the battery lasts).

    I ordered this item for a church kitchen. Essential to ensure safety of public from carbon monoxide poisoning.

    It has tested ok and appears to be in working order.
    It is a tidy design and moulding quality seems fair.
    Hopefully alarm will work should the emergency arise.

    Bought one as it was highlighted in a gas survey I was missing one. This meets the Industry standards/expectations.

    Does the job – flashes a light every now and then to tell you that its working.

    Have it freestanding on a table and is reassuring to have it.

    Highly recommended.

    Very easy to set up. No alarms so far but it has a light to confirm it’s working. Definitely worth the price

    Golden Review Award: 2 From Our UsersBattery operated so cannot say how long they will last. Design is quite nice, quite small. Big name behind it so hope it will work when needed. Loud but not too loud on “test”. But definitely will wake you up in a night. Recommended.

    Easy to install, comes with batteries too. Instructions easy to follow. Can be mounted discreetly so doesn’t look untidy. I have recently tested it and it made all the right noises so presume it’s doing it’s job.

    Golden Review Award: 3 From Our UsersI bought this after my last carbon monoxide monitor ran out. My boiler technician advised that they must be replaced on the date given. This is a nice small unit that was very easy to set up. Just pop in the batteries provided and press the big button on the front to test. It goes through a short bleep sequence so you know its working.
