    Advertised with 7 year warranty - box states 10 years!
    Replaced my old unit that is the same make and recently gave out. On opening the box the unit stated that lasts for 10 years not 7 years.

    You have no excuse for not having one of these in your home or more if you want, they are really easy to set up just stick the batteries in that are included and press the test button and that’s it just put it where you need it.
    I test mine once a week by pressing one button simply for peace of mind, it has a manufacturers date on it which is 2011 and that’s fine as it says renew every 10 years from activation which is you putting the batteries in. If you need one then get one.

    Seems decent and at a decent price. Some reviews mention it picks up gas leaks but this isn’t true. I haven’t wall mounted it as it is quite small plus I wanted to check the levels in the kitchen and in the location of our ancient boiler.

    Very loud. Just what you need
    I ordered a few of these to put in different rooms of the house. Easy to install and use, pretty much install and then forget (make sure to test periodically). The volume of them is LOUD. Which is what you want.

    I had an older version of these in our last house so went for these again when we moved.

    Just replaced my older one of these after having it for 7 years, on the advise of a gas engineer who said they ought to be replaced every 7 years. Went for the same type as never had any issues with the previous one. If you don’t have one of these, why not? Get one, it could save your life.

    Golden Review Award: 2 From Our UsersInsert the battery, locate it correctly, and forget about it. Simple.
    There’s really not a great deal to say about this. I guess I have to take it on good faith that it’s working well and will protect me if there’s a problem.

    Hopefully, it will just sit there and work away in the background – and for 99% of people who buy this, they won’t ever be aware that it’s there. So, because it’s one of those ‘install and forget’ pieces of kit, there’s not much more I can add.

    It looks good, it feels well made, and I hope to God it’s doing what it’s supposed to do. From my point of view, I’ve got it installed high up in the room (not too high – there’s some decent guidance provided in the leaflet), it’s out of sight and I really want to try to forget it’s there. So far, so good.

    I suppose the only way I’ll really know for sure that it’s working is if it sounds an alarm. In the meantime, all I’ve got to go on is the reliability and trustworthiness of the manufacturers name. And that seems OK to me.

    This is the no fuss one, and there's no need to fuss!
    Ok so there no full digital display, but there are 2 coloured LEDS and a test button. What more do you want, are you going to sit looking at it for its whole 10yr life? Comes with an initial set of alkaline batteries. All’s cool; just hope it works 🙂

  24. Haley8113rfrst says:

    Works and well priced
    Not a lot to say about this, since it seems to work fine, and is priced well.
    It doesn’t have a digital display like the more expensive ones, which can then show even non-dangerous levels of CO.
    However if you just want a cheap and cheerful basic detector, this should serve you just fine.

    Excellent, but may never be used!
    The item appears to be a perfect replacement for an expired unit. Installation was easy, taking care not to over-tighten the back-plate fixing screws to avoid distorting the plate. Pressing the test button confirmed correct operation by emitting a loud test-tone and bright warning lamp sequence.

    Golden Review Award: 6 From Our UsersEasy to install and good value
    Our old carbon monoxide detector had passed its life expectancy and had to be replaced.

    Easy to install and use, this is a very good value for money carbon monoxide alarm. It comes complete with alkaline batteries and same day delivery.

    The instructions are adequate and clear. There is also a 7 year warranty. The expected life span is 10 years and there is a space on the bottom to put the installation date.

    The device is CE certified and has a very LOUD alarm!

    At 10, this seems to be excellent value – especially when compared with high street prices and the 30+ British Gas wanted to charge me!
    I am more than pleased.

    Golden Review Award: 2 From Our UsersA must-have for every home, especially at this price
    I was rudely awoken by a British Gas employee who had been called out to my neighbour’s house regarding a suspected Carbon Monoxide Leak. The neighbour’s monoxide detector had triggered and called out the Gas Board, who could not locate any leak in their property – so investigated around my house.

    Given that I was genuinely asleep when he called and had had a boiler issue the prior weekend, I was a bit panicked thinking that I might have been getting gassed in my own own. Thankfully, there was no issue, but at that point I realised that my own carbon monoxide detector had expired earlier in the year – having owned it for about 15 years…

    So at that point, I made a snap decision to get one delivered next day by Amazon! Less than 24-hours later it arrived. It came with three batteries, ready to go. Everything was easy to set up and install. There’s a helpful test feature that you can acquaint yourself with to see how loud the alarm is, so I tested all this and placed it in the recommended spot around my boiler and cooker.

    Everything works perfectly so I’m very happy. The service from Amazon was good and the convenience of knowing that I could get the alarm the next day was good. At this price, there’s no reason that every house with a gas supply shouldn’t have one of these.
