    Grand job!
    Arrived quickly, came with batteries separate, easy to install, came with wall fittings but I used command strips so I didn’t have to drill holes. Nice and discrete but great peace of mind

    Package left out in the rain all day .
    I hope this product works when i finally dry it out. This package was not signed for and left out all day in the rain , I was in the house all day the box had disintegrated.

    Backplate same size as another Kidde monitor so no drilling just replaced one for the other. Hope batteries last longer than former one

    Arrived really quick. The item is guaranteed for 7 years but says discard after 10 years . Comes with batteries, so pleased about that . Looks sturdy and I hope it does the job. Value for money.

    Appears satisfactory
    I am assuming this works well – I won’t really know unless there is a leak.
    This was bought as a replacement for a 10 year old one which was no longer working.

    I can’t say whether it would work if carbon monoxide was detected as luckily none as been yet! However, it was extremely easy to install and the instructions were very clear. The intermittent green light gives you a nice reassurance that it is always on and working.

    The most reliable, best designed carbon monoxide detector on the marke
    I bought this to replace another “sealed battery” detector that was provided 4 years ago when our wood-burning stove was installed. One expects/hopes this kind of detector to last 10 years, like smoke alarms.

    This KIDDE CO detector inspires confidence – the bulb which flashes once a minute shows it is still working. And the sound when you press to test is LOUD. It looks and feels robust. Particularly the user CAN CHANGE THE BATTERIES! Liberating, and so one doesn’t have to spend another 13 or 15 to replace it, just replace the 3 x AA batteries at a cost ~3 (assuming you bought a bulk pack, like 12 cells).

    Well done KIDDE! (I’m not connected with them except for this purchase BTW)

    Fairly easy to fit to a wooden panel. Has been tested for real in an older person’s flat. It caused her to turn of the gas burners in a badly ventilated room. All is well now.

    No installarion necessary
    I was advised to install a carbon monoxide detector when I had my CH boiler serviced. I chose this one because it appeared to do all I needed and was relatively inexpensive. It arrived very quickly, the instructions were clear and it didn’t need any fixing as it could be placed on a set of bookshelves. There are however fixings to enable it to be fixed to a wall if required. Batteries were supplied so we were up and running in no time. There is a test button to check that the alarm is functioning and that the batteries are OK which I have tried a couple of times. The alarm sound is sufficiently loud and piercing as to be effective although I hope not to hear it again until its nest test! Would thoroughly recommend.

    QUICK AND EASY TO FIT. GOOD LOUD ALARM
    Our boiler is in the loft (we live in a bungalow) we don’t have any other gas appliances on the ground level so the alarm had to be fitted in the loft. I was concerned that we wouldn’t hear the alarm but on testing it it is very loud and can we hear it clearly in every room. Which is very reasurring. I have used kiddie products previously and have always found them reliable. The alarm comes with full instructions, batteries which you will need to fit and fixing screws and plugs. It was quick and easy to fit. I hope you found my review helpful.

    Easy instructions and ease of use
    After seeing the Amazon reviews, I bought three of these to replace my previous Carbon Monoxide detectors which were nearing their end. You install the batteries and are ready to go. Instructions are crystal clear and the noise is LOUD. I have kept it as a free standing detector instead of wall mounting it. The only downside with that is the real possibility that you might inadvertently press the test button and end up listening to the noise. Happened with me twice already!

    I prefer the smoke and CO alarms with replaceable batteries as have been caught out by ones with ‘7 years sealed for life’ lithium batteries which then last just a year or two. You then throw away the whole item just because the battery ran out. This item has powered up fine with the supplied AA batteries. I’ve no way of knowing if it will alarm if CO is detected, I’ve no way to test that. The self-test button works fine. I’m happy with the product.

    It’s super easy to set up, but oh my giddy aunt, get some earplugs before testing the noise on it! PIERCING. Louder than my fire alarms. Worst noise ever. But it works, and that’s what counts.
    Also: don’t place near cooker, it will go off when you click on the hob (if gas)
    don’t block the back or front of it, it will go off (needs ventilation)
    don’t put close to where you cook at all if possible, the build up of grease and steam water residue will make it go off.

    Easy to set up as not hard-wired. Can be set freestanding on a shelf so very easy to fit as no need to drill into the wall or ceiling unless you choose to. Good value too when I bought 2 to help us comply with the impending change to Scottish legislation on smoke and CO detectors which, unlike most legislation, looks like it will apply to all existing and new houses and not just new ones after the regs become law.

    Purchased to replace an expired one and I’ve had Kiddie products before and always found them to be reliable. Modern looking and discreet on a white wall. Good price.

    Best part was hiding the old one in the back of my brother-in-law’s pigsty of a builders van. Old ones beep every 3 minutes so he had hell of a job finding out where it was under 5 years of trash and tools.

    Easy to install, neat, loud alarm if activated, very reasonably priced.
    Never used one before, however, as our boiler is getting older we felt it important to have one, particularly as it is housed in an airing cupboard in an occupied bedroom. It was easy to test and install as there are 2 options – a wall, or freestanding. Having checked with our heating engineer when boiler was serviced, he approved my plan of placing it on top of the wardrobe approximately 2 metres from the boiler, where it now sits.
    Alarm is very neat, and makes no noise, well apart from when it would need to, and having tested it, it is very loud!
    Item was also very reasonably priced.

    The product itself is very simple to set up just make sure you have access to a window during set up as it requires fresh air to calibrate during the initial set up. The alarm is very loud and has an LED that blinks every so often to let you know it’s still working.

    Golden Review Award: 3 From Our UsersI'm saying it's good... but I don't really know
    So, first of all I’d like to point out that it says on my order list that this was handed to the resident. It wasn’t. It was left in front of my front door where anyone could have picked it up and walked away with it and I would never have known it was there. So, thanks useless delivery driver.

    Now that’s out of the way, the Carbonmonoxide Detector. So, it’s easy to setup. Take it out the box, put the three supplied batteries in and it beeps at you a few times. After your initial panic that you’re about to die, grab the little ‘Quick Setup Guide’ and read through and learn the beeps were good. After that, if you’re mounting it to a wall, mark out your holes, two drill holes, pop in the Rawl plugs (Yes, I spelled that right. Go check!) and hook your unit on it. If, like me, you live in a rented house and holes in walls = bad, then just pop it on a cupboard or something not too far from your potential death source ie boiler. Then, it just flashes once every 30 seconds. Job done.

    I hope I never need it and that this was a ‘waste’ of 13 but do you know what, it brings peace of mind. The flashing isn’t so bright that it wakes me up, but bright enough that when I’m getting dressed I notice it, which is all I need to know it’s still alive. I am not looking forward to the day the batteries die, as it apparently beeps every minute or so and the laws of sod say that this must happen at 3am in the middle of winter!

    I don’t know what to say on this one, the batteries are in, it tested well, and the light flashes every few seconds to show me it’s working. I am supposed to fix it somewhere between the boiler and cooker but that means the ceiling and then I won’t be able to get to it to change batteries or test, so I’ve stood it on the window ledge(non opening, so no draught) I hope that’s ok.

    Golden Review Award: 126 From Our UsersAn Excellent Decently Priced CO Alarm
    I don’t know about the rest of you folks, but I find it really helpful the many QUALITY REVIEWS I read about products on Amazon. That is what keeps me writing well-thought out reviews, as your many QUALITY REVIEWS have been of GREAT BENEFIT to me again & again. Thank you.

    Now for my Review Of the compact KIDDE CARBON MONOXIDE ALARM that comes with a 7 year warranty.

    I was quite wary (i.e. unsure) about getting another Carbon Monoxide Alarm, as many reviews of Carbon Monoxide were either EXCELLENT, GLOWING REPORTS or very negative ones. So I decided to read a lot of the Carbon Monoxide Alarm Reviews and ANALYSE the results. (i.e. break down my understanding of what they all meant)

    The KIDDE Carbon Monoxide Alarm seemed to get a mix of both positive and negative feedback. However, having carefully considered its feedback, I decided it was worth considering.

    The Compact KIDDE CARBON MONOXIDE Alarm is indeed very compact weighing approx 200g (0.44 ounces) and its dimensions being Width * Length * Thickness 7 * 12 * 3 cm 2.76 * 4.72 * 1.18 inches.

    It hardly takes up any space and although it comes with screws to affix it on a wall or ceiling, it has a ready-made slot on the back of the alarm to enable you to hang it on a hook or nail that’s partly recessed into a wall.

    The Carbon Monoxide Alarm comes with instructions and Three “AA” Size Batteries. It’s really easy to remove the cover to the battery compartment on the back of the Alarm. You just gently slide it down in the direction of the arrow and then put in the 3 * AA Batteries and then slide the compartment cover back on carefully. It’s important to note of course that it’s the actual Alarm Unit that comes with the 7 Year Warranty and NOT the batteries!

    You’ll probably need to change the batteries once every 7months to a year depending on HOW OFTEN the Carbon Monoxide Alarm sounds.

    [I say this as I’ve had a few KIDDE Carbon Monoxide Alarms in the past with at least two at any one time. Also, I believe that after about 5.5years or so, depending on HOW FREQUENTLY the Alarm goes off to alert you, the unit will need to be replaced as the CO Sensor inside the unit stops working!].

    And VERY IMPORTANT: WHEN YOU FIRST PUT IN THE BATTERIES, THE CARBON MONOXIDE ALARM MAKES TEN RAPID BEEPS, WHICH STARTLED ME A BIT. I should have read the instructions that came with the unit more carefully.

    You’re also advised to write in the date ON THE BACK OF THE UNIT, the date you installed the Carbon Monoxide Alarm & the batteries, as both the Unit and the batteries have a LIMITED LIFE SPAN. I installed mine on Sunday 26 July 2020 and wrote that date on the Carbon Monoxide Unit. I think it would be easier to write down the installation date with a marker pen.

    AND REMEMBER to TEST the unit AT LEAST once a week and PREPARE for the loud 85 Decibel Screeching Sound.

    Some Carbon Monoxide Alarm Units require you to vacuum their insides once every two to three months. I LIKE IT THAT THIS UNIT DOES NOT APPEAR TO REQUIRE THIS!

    Some people have complained about their own Carbon Monoxide Alarms received being manufactured a few years before they received them. The two I received were MANUFACTURED ON NOVEMBER 9 2019.

    Thanks for Reading and Hope you’ve Found MY REVIEW HELPFUL…

    Good replaceme
    I bought this because our other carbon monoxide alarm died one weekend, I thought it was the batteries but the problem persisted after I’d put new batteries in so I bought this one. Delivered as promised in good condition.

    Good unit but had dead batteries in the box
    Bought to replace identical unit that had triggered its 7 year end of life (bleep every 30s). Installed using supplied batteries and within 2 hours was bleeping with low battery warning (bleep every minute). Fitted new batteries and now ok. Date of manufacture jan 20 so wouldn’t have expected this.

    Returning buye
    Bought this to replace the exact one I bought years ago as it best to replace these types of devices after around 6 years.
    Hope I never need to take advantage of the alarm though.

    Keep your family safe
    i think all households should be made to have a carbon dioxide detector! such a deadly gas but so easily detected with something so small you dont really notice it.
    Great little gadget, so easy to install would recommend.

    It’s loud- so does the job of an alarm well I’d say
    Thankfully I’ve not had to actually test this in a real life situation so can only answer on how I anticipate it will work. It seems to work just as the instruction book says and the test button gives an uncomfortably loud beep so I’ve no doubt that it’ll wake me up from the deepest of slumbers should it need to.

    As necessary items that you hope you’ll never need go, it’s a good’un, would recommend.

    Testing button works. Haven't had a CO leak so unable to test that side of it.
    Easy to understand, testing button, beeps loud, have placed it on a shelf for the time being.
