Arrived quickly. Good price. Good, trusted brand. Well made. Good size so easy to position.
Does what it says and will continue to di so for 10 years before changing the battery required.
The peace of mind this monitor gives me is priceless.
Perfect piece of mind for the silent killer Carbon Monoxide. My last one lasted for the 10yr warranty period + 2 months so works out at approx 2 a year. Small price for a potential life saver. Screws and backplate come with it to allow for mounting to a solid wall
Me and my mate got one each for the campervan. Obviously it’s a small space with gas bottles. Camped last weekend and his went off during the night and obviously woke him up .Found out his gas bottle was leaking so might just have saved him and his sons life..For 20 it’s a nobrainer I won’t ever camp without mine again.
Thankfully the alarm has not gone off but it seems to be monitoring. It’s a safety product above all else. Seems to arrive in more of a trade pack than a retail pack but it came with batteries which it said were excluded so bonus there. You should be aware there is advice on where to fit the product if permanently mounting it.
I bought this because I have been regularly pestered to buy one. I have an ageing boiler so probably a wise move.
Not being able to test this against a CO source, I hope it works. I like the fact this unit retains a maximum PPM CO reading (until reset). Mine has only ever recorded 11 in this respect. I am guessing it is a quirk of the unit at low CO levels and possibly outside the precision of the sensor. Obviously, cannot comment on the battery life at such an early stage.
This is an excellent quality CO detector. It comes with duracell batteries and can be either installed in minutes or just stand free in the desired location.
Very clear readout.
Nice and small, easy to use and setup, digital display hasn’t shown anything other than zero which is a good thing. Easy to test and battery is lasting well so far. Provides another level of protection in the utility where the boiler is.
Got to have at least one of these for safty’s sake, we have three. One upstairs one by the boiler and one downstaires. I’ve had the one downstaires for the last 4 years and it still works fine, well it tests well…. Anyway these are well made and nice and clear to read. Odd thing though this latest one came with only a 7 year warrenty rather than a ten, hence only four stars.
Summary:
The Kidde 5DCO 10 Year Life Digital Display Carbon Monoxide Alarm is a reliable and efficient device that provides peace of mind with its advanced features. It is a must-have for every household for ensuring safety against carbon monoxide poisoning.
Positive:
1. The digital display is a standout feature, providing real-time carbon monoxide levels, which is a great advantage for immediate response.
2. The 10-year lifespan of the alarm is impressive and provides long-term security without the need for frequent replacements.
3. The alarm is easy to install and operate, making it user-friendly even for those who are not tech-savvy.
4. The device’s sensitivity to carbon monoxide is commendable, ensuring that even the slightest increase in levels is detected.
5. The alarm sound is loud and clear, ensuring that it can be heard from anywhere in the house.
Negative:
1. The device lacks a backlit display, making it difficult to read the carbon monoxide levels in low light or at night.
2. The alarm can be overly sensitive, sometimes triggering false alarms which can be a bit annoying.
3. The device does not come with a power backup option, which can be a concern during power outages.
4. The instructions manual could be more detailed for better understanding of the device’s features and operation.
Easy to install? Yeah – I just mounted it to the screws I had the previous monitor hanging from. IIRC batteries included with mine, so that was easy – just open the pack, and put them in the right way round.
Battery Life? Well, too soon to be sure, but our previous Kidde CO monitor was pretty good, so I expect this will be the same.
Easy to read? dunno – it is so straight forwards that I just bunged it on the wall. I think I read the manual for the post-installation test procedure, just to be sure.
Why did I buy this one?
Decent price, decent maker etc etc. This is the third monitor of the same make we have bought (they have a 7 to 10 year life span).
And the readout screen is nice, too. One can see a “sub-alarm” level – enough to show up, but not enough to trigger the alarm. Always nice to have that “heads up” that a problem may be approaching in the future.
Bought a refurbished range oven and, as it is gas, I doubled up on safety with this. Easy to setup and position. Test beep is loud and clear. Peace of mind for a good few years!
This is a replacement for another Kidde that had reached its end of life and was beeping. Test it once a week and it will protect you and your family from that most heinous and otherwise undetectable Carbon Monoxide gas for years. Money well spe
Bought to replace one that had failed under warranty,as it takes ages to get one under it. Like the idea of being able to take the batteries out and store it.
You cannot tell if it is working unless you have an escape of carbon monoxide. You have to trust it. It was easy to install. It has a readout that says zero which hopefully is correct. It is what I expected. I tried a different one a few weeks before that was rubbish and showed a fixed reading of 287. That was different brand and was returned for a refund.
I have a non display one that kept going off for no reason. I prefered one with a display, so you can see how much CO, if the alarm goes off. I have is just sat on a high up cupboard, so not fitting. Easy as that. Seems fine, good prices, happy.
I wanted another carbon monoxide detector as I was advised that another was important as I have now other gas appliances. For safety’s sake these should be mandatory if having any gas appliances. It was easy to install and would recommend as this is my second one. Well priced.
Great detector for my camper van since having a diesel heater fitted, comes with all fixings and good instructions
This is our 2nd meter, a mere 10 year gap between orders! Easy to use and carry out weekly testing to ensure all is well! Great for peace of mind. Will buy again in 10 years.
Bought this to replace another make that was faulty when it arrived. Feels much better made and was very easy to install and set up.
Made by Kidde, a company I have known all my working life for fire prevention equipment, I feel safe using their products.
No issue, easy the install, a must, even in these tuff times.
easy to set up, and provides security from carbon monoxide poisoning in bedroom above boiler.
purchased this item to as a second product in the house! easy to use and modern look
Speed of delivery very good and set it up easily for my father, but not wall mounted – free standing on high shelf in kitchen. Self test feature is useful and clear instructions.
Included batteries were very low in power. Had to replace them.
My only criticism is that for some inexplicable reason the printed details explaining what the various beeps mean is printed on the inside of the rear cover . This means that you would have to remove the back cover if using free standing or remove the device from the rear cover if fixed to the wall to then read the faintly printed explanatory codes. I will be keeping the information sheet or at least a transcription of the information near to the device. I’m sure that it wouldn’t detract too much from the appearance of the device for the information to be printed in a more accessible site on the casing. Otherwise very good
Spoiled a bit as the display is not fitted in straight so looks cheap Also, you don’t get warned that the batteries have to be renewed yearly. I thought this would come with long life batteries. Also, how can a 10 year life be claimed when it only has a 7 year guarantee?
Product needed for our static caravan, previous one had gone past it’s 7 year life expectancy. Just arrived 2 days ago so gave not had chance to set up and install in caravan. If it lives up to the previous Kidde alarm then it will be value for money.
Fitting wasn’t that easy for me because it had a bigger form factor than the one it replaced so a bit of fiddling around was needed!
It’s been great on battery life and performs well, when we had the boiler serviced the operative said it was a decent unit.
Fast next day delivery whilst on holiday turns out the smell was a septic tank toilet who’d of thought i
Very easy to install. As for battery life, as I only installed the units a few weeks ago it’s much, much too early to tell ! Good value for what I paid, fingers crossed they will be effective in the event of a carbon monoxide leak, but let’s hope I don’t find out.
A real no brainer. Cheap and silently does it job. Hope it is never needed.
Be aware there are certain places you cannot place it, so read the instructions before installing.
Good detector, which is always on guard, once up it becomes part of the environment, until it goes off. Excelle
Bought this to replace another brand. Easy install, excellent value and fast shipping. 5*
Excellent value and definitely easy to install. Would buy again. Works very well.
Purchased a twin pack, one for next to the boiler and one upstairs.
Both very easy to set up, have a long battery life and will certainly raise the alarm is required.
As advertised and on time and it works but how well only time will tell, has a reassuring flashing led to show it is working.
The product came ready to go. insert the batteries supplied and hang on the wall. Another 10 years sorted.
Happy with this item. Was easy to set up and works as it should.
Advert is confusing as it states 10 years life, yet its warranty is only 7 years.
Battery life not yet Known. Is blinking the green light OK.
Our previous CO Monitor was near to the end of its 10 year life when it went off. (Our water heater was condemned and turned off) We bought the same monitor with the up grade of a digital counter.
Feel very happy to have the same confidence with the new one.
Happy to be here to say so, and are very happy to recommend this product.
I only had one by my boiler and read that all appliances should have one. So I already have a Kiddie sensor so I ordered one for the kitchen so now my cooker and hob are covered. All you need to do is fit the batteries which are supplied and attach to wall or cupboard yes the screws are also supplied. Very pleased
As described. No idea on battery life yet but assume will be fine.
The British Gas boiler-maintenance guy told me (while fixing me with his most serious frown) the CO detector I had wasn’t tested the British Standard. So I bought this one.
Hard to know what to say: the alarm hasn’t gone-off while nothing was happening so no false positives; and as we’re not dead the alarm hasn’t failed to go off when there was a lot of CO about so no false negatives either.
Mounted this one next to a boiler as requested by landlord of a rental property.
Easy to install, clear display, good battery life.
From a trusted brand, I’ve used Kidde for a number of years and never had any issues or problems with their products, not the cheapest but why compromise quality on something this important, and they are actually reasonably priced anyway.
RECOMMENDED.
I bought a few of these when my daughter started complaining of feeling sickly and dizzy all the time.
Place them near the boiler, gas fire, and in her room just to rule out any carbon monoxide leaks. I like the display as it will tell you not only if carbon monoxide is leaking but at what rate,
General alarms just go off and you can’t tell if they are faulty of if there is an escape.
Put one in the car to take on our holidays when we are staying at a caravan as these older boilers are notorious for leaks if not maintained. Better safe than sorry for such a small price.
I like the display, gives you more assurance when the battery is dying/the product is reaching end of life if it’s a detecting gas or not.
A very useful tool, reasonably priced, inconspicuous yet very informative in regard to domestic safety. Every home with wood, coal, gas or oil burning fires should have one
It was very easy to install – just put the batteries in and press the test button and you are ready to go!
Unlike our previous alarm which had date expired, this one has a digital display in addition to the alarm which adds confidence and a quick visual check to ensure that’s its actually still working. Neat little unit.
Nice product, visually good and easy to use. I got this one for the 10 year life, I just placed it where I needed to. Now its set I can forget about it and have peace of mind that if there is any carbon monoxide this will let me know. Must have!
I use this in my hot tent, and although it is not the smallest, I chose this one from several review sites that recommend it for its reliability and long lasting battery which is most important. It is good value and arrived quickly. The digital display is clear, and the alarm is loud, so if you want peace of mind, you cannot go wrong with this one.
easy to set up, looks like its doing its thing, and delivered promptly. With all of these thgins you hope to never hear them go off in anger!
I confirmed accuracy of my unit by comparing against my Kane Flue Gas Analyser. I found it to be accurate. Other than that, the alarm is suitably annoying which is just as it should be
We like the Kidde digital display carbon monoxide alarm. It was easy to assemble, and to understand the instructions. And it look very neat, we are very happy with our purchase thank you
Positioned outside the cupboard that houses the boiler. Easy to install and gives great peace of mind.
Bought for my old Coal heated house and seems to be working fine.Easy to install and setup.
I would definitely recommend this. This is the second one I have had. They have a 7 year life due to the carbon sensor lifetime. I bought the first one obviously 7 years ago and it gave excellent service and so I replaced it with the same. Easy to install and very minimum maintenance ie only the batteries to replace
I like this item had one before and was very pleased with it, not sure how long it lasted as was sold with my caravan. Have not had this one long enough to tell about battery life. Thank You for the quick service.
This seems like a good quality product. I have it near a gas fire to monitor for any CO leakages. I can’t comment on the battery life, however, as I have only had this for a short time. Maybe I’ll update the review in 7 years’ time.
In the meanwhile, it seems like a good product and is easy to test.
After having our boiler serviced, our gas engineer recommended this as one of the best on the market.
Was easy to fit, looks good and of course it gives peace of mind! Would definitely recommend having one.
Replaced one that lasted 7yrs!!
Still uses same backplate so an easy change.
Who knew these had a shelf life?? I kept replacing batteries in old 1 and it went crazy couldn’t work out why!!
Anyway during a new boiler installation I mentioned it to plumber who advised the shelf life issue! Bought this one and works like a treat!
Easy to install just insert the batteries which is included and you will hear beep from device don’t worry the numbers on the screen will change to 0 and the GREEN LIGHT FLASHING EVERY 30 SECOND.
I place it near the boiler.
Highly recommend it for every Home
Looks a good product: it’s one of those items (like a fire extinguisher), that you won’t know how good it is
until you have a problem!
This device is supposed to detect and warn of the presence of carbon monoxide (CO), which should not be three to be detected. So in practice its expected function is to display a comforting zero. It does that perfectly; I trust that if there is a significant amount of CO gthen it will raise the alarm.
THis is quite a nicely designed device. There is a clever arrangement that makes it difficult to put it together if there are no batteries inside. The backplate doubles as the battery compartment cover and the wall mounting bracket. You can mount it with screws or just stick it up, or, as we did, put it inconspicuously on a suitable shelf. The alarm sound is shrill and quite loud – as you’d expect it’s like a typical battery powered smoke alarm.
Only brought item yesterday. Realistically don’t know how long battery life will last or how good item is until had for few years. However it looks good
With just one meter, reading “0” how do i know that its functioning. However, its up and running and making potentially life saving analysis in real time. I thnk i should have bought two.
Living in a small flat with gas central heating, I decided it prudent to have a decent carbon monoxide tester, especially one with a read-out, to be able to see what the level is, if any. Easy to install, quick test to make sure it works and that’s it. Sits on the side monitoring, silently … let’s hope it doesn’t have a need to sound off.
A great carbon monoxide alarm coupled with a 10 year sensor and a 7 year warranty from a trusted brand, in my mind every home should have these whether you have central heating or an open fire /wood burner. Very easy to install and comes with duracell batteries. Also comes with screws and wall plugs. Alarm is very loud and a green light flashes every 30 seconds to let you no its working also has an lcd read out.
For many years just been using the simple dot on a square that never seemed reliable. Just had my boiler serviced and the engineer reminded me to get a detector and decided to review.
Why didn’t I do this years ago, for 15 a 10 year device that could save your life? This should be mandatory in any home with a gas appliance IMO.
Quality product, supplied with Duracell batteries. Batteries in, and it works, simple as. Nice loud audible alarm. Peace of mind for 15 can’t be argued with. Reviews suggested this was the one to go with and wasn’t disappointed. Delivered to Amazon locker no problem as well.
Brilliant little alarm. My old one went off randomly the other day and after re setting it was fine. So I wanted a digital one that actually tells you if it detects any carbon monoxide and how much. Mine hasn’t detected any luckily but I like seeing ‘0’ on the screen as this gives me reassurance. Alarm is loud so you won’t miss it and it blinks to show it has power and let’s you know when it needs new batteries.
It arrived as predicted and is as described. it was easy to install the batteries, but docked a star as I have no idea how long they last. It came with screws and rawlplugs which were small and very quick to drill and install on the wall.
It is now fitted and working, the noise on test is loud as you would wish. Fingers crossed it will work, but I hope I never have to find out.
Yes, its not the cheapest carbon monoxide alarm but the extra features more than make up for the small extra cost so in my view is good value for money. You can’t put a value on life so investing in a decent alarm is an absolute must for peace of mind. It’s so easy to fit & use & it now sits quietly working away & so far has nor required any attention.
I am using it for the purpose for which it was intended, I bought two the 2nd for my daughter’s household. My previous review was for another product and a different seller and was entered in error.Comes from using a small screen with large fingers! I’m not sure if it has been removed if not please ignore. There is nothing wrong with this product or the seller both are absolutely fine.
Having just fitted a wood burning stove to our log cabin, I thought it prudent to install a CO alarm.
While this one was a couple of pounds more expensive than some others, it does have the bonus of a digital display, so we may well get advanced notice of my chimney fitting skills being sub par before the alarm actually sounds!
Hopefully it’ll never happen – but a few pounds for peace of mind is money well spent.
I thought the build quality was down on the same device of ten years ago, e.g. sticky labels instead of mouldings. It would have been nice if the label had been squared up instead of on the slant missing where it was meant to go – speed of production maybe? That said the guts seem fine, which is what matters after all.
I was a little uneasy that the old detector (same model) might have stopped detecting earlier than indicated by the alarm noise, as the digital display did not show “END”, but was ambiguous. I changed the batteries to make sure anyway.
Ten years ago the instructions referred to a back light which wasn’t there, the detector before that did have a backlight (this is our third) which was handy. No backlight this time, but no reference eithe
I chose this monitor as the digital display makes it more obvious if it’s working etc, and it was very easy to install. Looks neat, and the info booklet is really comprehensive and written clearly. I feel confident in its efficiency.
For the past couple of weeks my husband and I have been experiencing headaches and feeling sick. We noticed an odd smell near our back boiler system which occurred when the boiler came on. It didn’t smell like gas. We had a CO monitor which was not being activated by the fumes, so we didn’t think it was that, but called a gas engineer who advised calling the emergency gas line. They sent an engineer out within 20 minutes, and his detector confirmed a high level of CO, which had not been detected by our monitor! He had to turn our gas off at the supply and mark it as unsafe. An advised trip to A&E confirmed we were ok, (phew) and a local gas safe engineer came this afternoon to do a full investigation for us. Turns out our boiler has a crack in the burner, which had led to rapid soot build up which in turn blocked the flue and prevented the CO and other fumes from exiting via the chimney. It has now been decommissioned and we’re getting quotes for a new boiler.
That is the way with detectors, you are buying peace of mind and you want them to run smoothly in the background with minimal attention. You do not want upheaval, a lengthy fitting process or constant maintenance.
So far this detector has done everything right, so I have every hope it will last for years.
It’s not worth skimping on your safety with something when it comes to something like this – I’ve got a real horror story form friends who didn’t have a working carbon monoxide alarm and only just managed to get out of their bungalow when they realised what was happening. Tragically around 50 people die in the UK each year from carbon monoxide poisoning, don’t let your loved ones become a statistic when it’s easily preventable with a good quality alarm.
