    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.
