Review of the Kidde 10SCO Combination Smoke & CO Alarm
Typical price: £16.00
Test outcome: PASS
Home Safety
Comparative judgement: Excellent
Both smoke and carbon monoxide can be detected with the Kidde 10SCO combo smoke and CO alarm. This evaluation describes how well it performed in our testing when put to the test to find carbon monoxide back in 2018. It has a 10-year warranty, a 9-volt battery powers it, and it will sound to let you know when its useful life is through. To learn how this Kidde smoke and CO alarm performed in our detection tests, continue reading our entire review.
Excellent in detecting every level of CO we tested it with and keeps making reliable sounds even after being exposed to a lot of CO. It continued to function well three months later.
Cons
None that we discovered during our tests; this alert always went off at the appropriate moment.
In our tests, this Kidde alarm did a great job of detecting carbon monoxide. We gave it the task of detecting a rising concentration of the gas, up to levels that could be lethal, starting at a very low level where the alarm shouldn’t ring. The Kidde 10SCO passed every test we gave it, so we’re delighted to name it a Best Buy for carbon monoxide alarms. It wasn’t awful at all as a smoke alarm, but it was barely shy of Best Buy level. Don’t be concerned that this alarm isn’t brand-new; even though it’s a 2018 model, it’s still one of the top models we’ve tested.

Typical price: £8.99
Test outcome: FAIL
Alarm
Alarm
Verdict in comparison: Unresponsive to carbon monoxide – Don’t Purchase
Between 2016 and 2018, we tested six alarms that resemble the one seen here, and none of them successfully detected the presence of carbon monoxide. If your home’s CO alarm resembles the one in the image, you should replace it because our testing reveal that it’s probably harmful. Based on the six seemingly identical alarms that failed our CO tests, we have issued a Don’t Buy caution for alarms that resemble this one.
There are no benefits to purchasing this faulty carbon monoxide alarm.
Cons
Everything we’ve observed during testing indicates that carbon monoxide detection cannot be depended upon with alarms that look like this (CO).
Similar-looking alarms may have an unfamiliar brand name or be unbranded, and the packaging may differ from one alarm to the next. However, everything we’ve observed in our tests on six alarms that like this one leads us to assume that they are the same devices and frequently miss carbon monoxide leaks. We tested six different iterations of this alarm that we purchased from Amazon and eBay for less than £10. Both in 2016 and again in 2018, none of the alarms we tested were capable of accurately detecting carbon monoxide. As a result, we have designated all alarms with this design as Don’t Buys.
Every alarm we’ve tested has arrived with incorrect installation instructions that tell customers not to put the alarm in the kitchen, which is where many UK houses have a gas boiler that might be a source of carbon monoxide (CO).
Unbranded Review of Carbon monoxide alarm 2
Typical price: £6.00
Test outcome: FAIL
monoxide alarm
judgement in comparison: Don’t Buy since it doesn’t always detect CO
Despite failing to detect CO in two of our tests, this carbon monoxide (CO) alarm is deadly.
We have declared it a Don’t Buy as a result of these gas detection failures, and we strongly advise you to stay away from it. If you already have one, you should swap it out for a well-known brand from a trusted high-street retailer or online merchant.
None; this alarm is harmful and should not be used.
Cons
unable to accurately detect carbon monoxide
Ineffective and maybe harmful directions.
Don’t Purchase this unbranded, hazardous carbon monoxide alarm. In two of our CO detection tests, it was unable to identify the lethal gas. In the failed tests, it was tested with a catastrophic CO concentration to see if it could recover and resume regular operation. In our tests, we discovered that it failed to both detect a significant amount of CO and a smaller concentration of CO before failing to do so and sounding the alarm. Because of these problems with the gas detection, we’ve declared it a Don’t Buy.
Unbranded Review of the CO Alarm 3
£11.00 is a common cost
Test outcome: FAIL
CO Alarm 3
CO Alarm 3
Comparative conclusion: Three of our tests failed to identify carbon monoxide.
In one of our early testing for carbon monoxide detection, this carbon monoxide (CO) alarm failed to sound. It also failed to respond and sound the alarm in two additional gas tests. We have thus designated it as a Don’t Buy. It appears unbranded in some lists while other listings refer to it as the JKD-512COM. Our research indicates that you can’t always rely on it to detect carbon monoxide, therefore we recommend keeping a fairly wide distance from it. If you already have one, get rid of it as soon as you can and get a trustworthy brand-name alarm from a high-end retailer on the main street or an established online merchant.
Cons
This alarm cannot properly detect carbon monoxide.
Our tests have a poor ability to detect carbon monoxide
overly quiet
Ineffective and maybe harmful directions.
In three of our tests for gas detection, this unbranded carbon monoxide (CO) alarm failed to detect CO. The first time it failed was when we challenged it to find a small amount of gas that could be fatal. Later failures were noted when it first missed a huge concentration of the gas before missing one with a smaller concentration. We have designated this alarm as a Don’t Buy because the repercussions of it failing to sound in your house when you need it to don’t even worth thinking about.

Unbranded Review of the CO Alarm 4
£11.00 is a common cost
Test outcome: FAIL
CO Alarm 4
Avoid this alarm – Don’t Buy, in comparison.
You cannot rely on this hazardous carbon monoxide (CO) alarm to detect CO and then sound the alarm when you need it to. We are making it a Don’t Buy because of this. It can’t be relied upon to warn you if a buildup of the lethal gas has occurred in your house because it failed to identify CO in 17 of our detection tests. If you now own this alarm, you ought to swap it out as soon as you can for a model made by a reputable company.
Cons
None; having one of these alarms in your home puts your life in danger.
unable to accurately detect carbon monoxide
overly quiet
perhaps dangerous instructions
17 of our CO detection tests on this dangerous carbon monoxide (CO) alarm were negative. Additionally, the instructions don’t adhere to the standards for carbon monoxide alarms, and when the alarm does go off, it is excessively quiet. Therefore, this cheap and unpleasant alarm is the definition of a Don’t Buy and is to be avoided.
Unbranded Review of Carbon monoxide alarm 5
£5.00 is a common cost
Test outcome: FAIL
monoxide alarm 5
monoxide alarm 5
verdict: Don’t buy because it is unreliable at detecting carbon monoxide.
This carbon monoxide (CO) alarm, purchased from an online market, is just another unreliable carbon monoxide (CO) alarm that is inexpensive and unbranded. Our test results indicate that after three times of failing to detect CO, it is more likely to jeopardise lives than to save them, hence we have declared it a Don’t Buy. If you already have one in your home, swap it out for an alarm from a trustworthy online or high-street retailer and a well-known brand.
Cons
This hazardous alert isn’t sensitive enough to consistently detect CO.
We found very little CO during our tests.
Three of our tests for CO detection revealed that this alarm was flimsy, unpleasant, and most importantly harmful. The instructions also provide incorrect information regarding where to site it. It didn’t sound when there was a lot of CO present, and it didn’t sound again when there was less CO present. The alarm failed to detect the gas once more during our 90-day test, which includes testing it on both day 1 and day 90. This alarm would simply be unable to detect CO with sufficient accuracy if the findings of our tests were replicated in your home. Because of this, we have marked it as a Don’t Buy and are alerting customers about it.
Review of the Lifesaver 5CO Carbon Monoxide Alarm
Typical price: £17.00
Test outcome: PASS
Carbon Monoxide Alarm
Verdict on comparison: Excellent
During its seven-year lifespan, you will need to replace the disposable batteries that come with the Lifesaver Carbon Monoxide Alarm 5CO every two to three years. You would anticipate being able to rely on the Lifesaver Carbon Monoxide Alarm to live up to its comforting name in exchange for this maintenance. We put this trust to the test against four different concentrations of the toxic gas in our test lab back in 2016 to see if it held up. For the findings of our evaluation of this Lifesaver carbon monoxide alarm, continue reading.
Advantageous for detecting carbon monoxide at all concentrations
loud enough for everyone to hear while being durable enough to recover from a catastrophic gas incident and continue to function properly.
Cons
None. The three months of testing for this alarm revealed no flaws.
This dependable, loud carbon monoxide alarm earned a Best Buy rating after excelling in our tests. It worked just as well at the end of our three months of testing as it did at the beginning, and it detected all levels of carbon monoxide in our 30+ lab tests. It also recovered well from exposure to a significant amount of the gas and was able to sound once again. Therefore, don’t let the fact that it is a few years old stop you from purchasing a top-notch carbon monoxide alarm.
Unbranded Review of the CO alarm 6

Verdict in comparison: Extremely unresponsive – Don’t Buy
This dangerous carbon monoxide (CO) alarm registered 37 failures to detect CO and sound the alarm during our testing, so we are rating it as a Don’t Buy. Although it can also be found on other internet markets, we acquired it from eBay. You just can’t rely on it to detect carbon monoxide when you need it to, much like a number of other inexpensive and unbranded alarms we have purchased and tested through this type of website. Replace any alarms in your home that resemble this one with well-known models from a high-end retailer on the main street or an established online merchant.
None; this smoke alarm is terribly unreliable.
incapability to accurately and consistently detect carbon monoxide
overly quiet
Ineffective and maybe harmful directions.
This is another carbon monoxide (CO) alarm we purchased from an online store that is unresponsive and plain dangerous. It failed all but one of our tests for CO detection, so you simply couldn’t rely on it to warn you in your house about a potentially fatal buildup of the gas. When it does sound, it is far too quiet, and the directions could be misinterpreted. This alarm is among the more unsettling and hazardous goods we’ve examined; as a result, we’ve given it the Don’t Buy label and strongly encourage you not to purchase it.

This amazing carbon monoxide detector passed every one of the more than 30 gas detection tests we gave it, including ones for low, medium, and high amounts of the gas. We loved that it was just as effective at detecting carbon monoxide on day 90 of our tests as it was on day one. It was loud enough to wake up the entire home. Overall, despite its advanced age, a definite Best Buy and one for your shortlist.
Unbranded Review of Carbon monoxide Alarm 8
Typical price: £8.00
Test outcome: FAIL
monoxide Alarm 8
monoxide Alarm 8
Verdict in comparison: Extremely unresponsive – Don’t Buy
Avoid using this carbon monoxide alarm, which is marked “Don’t Buy.” In our tests, it missed the fatal gas 27 times, which is concerning. It also functions as a smoke alarm, as seen at https://www.which.co.uk/reviews/smoke-alarms/unbranded-smoke-alarm-in-blue-box. And when we tested its ability to detect smoke, it performed equally poorly. However, you can also find it advertised on other comparable online markets. We purchased it from a seller on eBay. If you already have one, swap it out for a well-known brand from the high street or a trustworthy internet retailer.
Cons This alarm is harmful and should be avoided.
Cons
not accurate enough to properly detect carbon monoxide.
One of the most hazardous products we’ve ever examined is this alarm. We’ve tested it in both smoke alarm and carbon monoxide detector modes throughout the past year. It failed to beep in any of our eight smoke detection tests as a smoke alarm. Additionally, out of the 38 CO detection tests we conducted, it failed to sound 27 times. Even when it does sound, it is much too quiet. One of the most blatant Don’t Buys we’ve encountered, it should definitely be avoided.
X-Sense CO03D review
typical price £25.00
Test outcome: FAIL
X-Sense CO03D
X-Sense CO03D
judgement in comparison: Never detected CO – Don’t Buy
In one of our carbon monoxide tests in 2018, the X-Sense CO03D carbon monoxide alarm did not sound. We have designated this X-Sense alarm as a Don’t Buy due to the safety issues we have based on the gas detection failure in our tests. All three of the alarm samples we tested failed in the same way when exposed to a catastrophic level of carbon monoxide, including this device.
Pros
It passed all but one of our carbon monoxide tests while failing the other ones. But it only takes one failure for us to put a Don’t Buy notice on something.
Cons
Because none of the three samples found a significant amount of carbon monoxide, we have rated this device as a Don’t Buy.
This alarm performed admirably in almost all of our carbon monoxide detection tests, but because it failed to pick up CO even when exposed to extremely high levels of the deadly gas, we have given it the Don’t Buy designation. Your best option is to pass on this model and use a carbon monoxide alarm from Best Buy in its instead.

Cons
None. No flaws with this alarm were discovered throughout our three-month tests.
Withstanding more than 30 gas tests, this outstanding carbon monoxide alarm always sounded its alert at the appropriate time. It is sturdy and dependable, and it features a loud alarm. The fact that it maintained the same level of sensitivity to the CO threat 90 days into our tests makes it a worthy Best Buy. Don’t let age be a deterrent since even though we tested it back in 2016, it’s still one of the greatest carbon monoxide alarms we’ve ever seen.
Aico Ei208 review
£21.00 is a common cost
Test outcome: FAIL
Aico Ei208
Aico Ei208
Verdict in comparison: Inadequate in our testing
We designated the Aico Ei208 carbon monoxide alarm as a Don’t Buy because it failed to beep during one of our 2018 carbon monoxide testing. In one of our experiments, we successfully activated and sounded three of the Aico alarms by flooding them with a catastrophic amount of carbon monoxide. However, none of the three sirens activated later when we tested them with a lower but still deadly dose of the gas. Aico expressed concern, said it takes issues with alarm quality and dependability very seriously, that all of its alarms are independently tested, that it hasn’t encountered any issues with these alarms since they were introduced in 2010, and that it is confident that its alarms comply with the carbon monoxide alarms standard.
Pros
Aside from one test, this alarm passed all of them. However, we have declared it a Don’t Buy due to the gas detection failure we discovered in one of our testing.
Cons
The alarm was exposed to a very high level of CO but failed to recover and sound.
This Aico alarm has been marked as a Don’t Buy due to the fact that it failed one of our tests for carbon monoxide detection. It passed all of our other carbon monoxide detection tests, but after being exposed to an extremely high carbon monoxide concentration, it was unable to recover and maintain a reliable sound.
Review of the Kidde Long Life Carbon Monoxide Alarm 10LLCO
£18.00 is a common cost
Test outcome: PASS
Monoxide Alarm 10LLCO
Comparative judgement: First-rate
The Kidde Long Life Carbon Monoxide Alarm 10LLCO’s name gives it away: you shouldn’t need to replace it for up to 10 years. The batteries, which are securely sealed inside the device, won’t even need to be changed along the road. Does it, however, combine this lengthy lifespan with the capacity to identify even minute amounts of carbon monoxide in the air? Back in 2016, we conducted a series of gas detection tests on the Kidde carbon monoxide detector to find out.
Pros
four different intensities of carbon monoxide were successfully detected
Loud
capable of withstanding exposure to carbon monoxide and rebounding to resume reliable operation.
Cons
None. During the three months of testing, this alarm showed no flaws.
When we tested this Kidde carbon monoxide alarm in our lab in 2016, it did an excellent job of spotting the deadly gas. And even when exposed to extremely high carbon monoxide levels, it recovered quickly and continued to function dependably. Its 10-year lifespan is astounding, and it is as loud as an alarm should be.
Review of the Nest Protect Smoke + CO Alarm
Typical price: £89.00
Test outcome: PASS
Smoke + CO Alarm
Verdict on comparison: Truly excellent
If you’re away from home at the time, the Nest Protect Smoke + CO Alarm can send notifications about dangerous amounts of smoke or carbon monoxide directly to your smartphone. The price of this more sophisticated two-in-one CO alarm is significantly higher than the cost of a normal CO alarm due to its 10-year lifespan and additional capabilities. This evaluation focuses on how well the Nest detects CO, however it also functions as a smoke alarm, and since we tested it, Scotland’s smoke alarm regulations have changed. This means that starting in 2022, Scottish homeowners won’t be able to use the Nest because it lacks a heat detecting feature. To determine how successfully the Nest Protect Smoke + CO Alarm detects carbon monoxide, we subject it to a battery of rigorous safety detection tests. The outcomes of our testing are listed below.
Pros
The mobile alerts are effective.
It works well at identifying different carbon monoxide concentrations.
withstands incredibly high gas concentrations and is audible to everyone.
Cons
just the exorbitant cost
But it has two goods in one and has a 10-year lifespan.
An inventive gadget that, in our tests, performed flawlessly as a carbon monoxide alarm. The alarm went off as planned, and around 30 seconds later, our smartphone received a message. In our tests, it was just as effective at detecting the gas on day 90 as it was on day 1. It is loud enough. It is also a Best Buy as a smoke detector, but starting in 2022 it won’t be acceptable for use in Scottish houses as one due to a change in Scottish law.

more expensive than a CO alarm powered by batteries.
This Best Buy CO alarm is a superb mains-powered CO alarm. In all of our CO gas detection tests, it did a great job of picking up the gas and sounding the warning. Regardless of whether it was tested with low or high CO concentrations, it was well able to detect the gas and sound the alarm. It maintained reliable detection even after being thoroughly saturated with the gas. It was more than loud enough and still dependable 90 days into our tests.
Honeywell XC100 review
typical price £25.00
Test outcome: PASS
Honeywell XC100
Conclusion: An excellent CO alarm
Longevity is a priority in the design of the Honeywell XC100 carbon monoxide alarm. You won’t have to worry about obtaining replacement batteries for it because it comes with a sealed-in and tamper-proof 10-year battery. Additionally, it has a red warning sign that is backlit and visible through the case. The Honeywell emits a sound and flashes the words “Alarm evacuate” when CO is present. However, how accurate is the carbon monoxide detection? We put it to the test back in 2018 to find out. For the complete results, keep reading.
Pros In our tests, it consistently sounded the alarm when carbon monoxide levels reached a dangerous level.
Cons
None of them emerged during our tests.
This carbon monoxide alarm may be a little dated, but it’s still highly effective. We gave it a variety of concentrations to identify, ranging from very low levels where the alarm isn’t need to sound all the way up to disastrous amounts and everything in between. In every one of our testing, this excellent alarm went off when it was supposed to, was loud enough, and maintained its quality three months later. And for that reason, it is a Best Buy.
