    The only minor problem was fitting the batteries with arthritic fingers, they required a hefty push

    I’ve had these installed 20 years ago. A house fire started across the road and the fire brigade dropped a leaflet through the door recommending to replace smoke alarms every few years. I bought the the same one as last time.

    Just installed today to replace older model of same alarm. Only one fault. One of the batteries keeps coming out of place in the middle. There are 3 altogether. However when in situ alarm appears to work correctly.

    We were advised by our gas boiler engineer to get a Carbon Monoxide Alarm as the gas boiler was in the vicinity of our bedrooms .

    It was so easy to fit , matched our decor and should last for 10 years.
    Good value for money .

    Easy to set up, with clear instructions, however unsure about 10 year life as advertised, clearly states 7 years . A simple basic device, but why pay more as long as it warns you that’s all you want . Satisfied.

    Good price easy to test and set up. Wall mountable or free standing. Don’t know if the battery will last 10 years but who cares if it doesn’t its a small price to pay for something that could save your life.

    Really happy with the purchase – hard to review fully as unless it ever goes off how do you know it works???
    But easy to set up, easy to test, I was happy with the price, it arrived next day. It’s quite small, approx the size of an iPhone on its side and it’s white so I’ve popped it on a shelf without looking too unsightly – hopefully worth every penny

    Compact and easy to install. Comes with the necessary fixing. I screwed into drywall without the stud (location of the stud was not aesthetically suitable) but this was not an issue given this unit is light enough to hold tight.

    I bought this product to provide detection of carbon monoxide. 2 years down the line, it is working fine. Simple design and good value for the cost.

    Ten minutes to install, instructions very clear. Just remember the battery does need replacing periodically, however the unit beeps when the battery life is low.

    Bought this when I moved into my new house and it was really easy to set up. I have it in the cupboard with the boiler so I haven’t had to attach it to the wall, but it looks easy enough to do. The batteries haven’t needed to be changed in over 7 months so you really can just set it up and let it do its job without thinking about it. When I first set it up I did use the test function just so I would know what it sounds like and you would definitely know if you had a problem since it is so loud – which is exactly what you want from a Carbon Monoxide alarm! I would definitely recommend getting one for peace of mind!

    I bought this to replace a ten year old version, so at a cost of about 1 or 2 per year worked out to be inexpensive peace of mind.
    Easy to fit – has a back plate you hook over a screw head.
    Came with a set of batteries which you can test to see if and when they need replacements.
    Simple, easy to use, good longevity.

    Replaced my 10 year old version which was still working !
