eBay and Amazon Delist Faulty Carbon Monoxide Alarms (theguardian.com) 78
An anonymous reader quotes the Guardian:
Dozens of potentially deadly carbon monoxide alarms have been removed from sale by Amazon and eBay after a Which? investigation found some of them would not have protected their buyers. The consumer group tested four alarms that were on sale on both sites -- including an Amazon bestseller -- and found that they consistently failed to sound when the gas was present.... It said one of the alarms -- the Topolek GEHS007AW CO alarm (£14.99) -- was listed as a bestseller on Amazon. It failed to detect the gas in more than 80% of tests. Three other unbranded alarms that were made in China and sold through sellers on Amazon and eBay for under £10 also repeatedly failed to sound when there was carbon monoxide present... Which? said all four claimed to meet the British safety standard for detecting carbon monoxide.
Both Amazon and eBay have now removed the alarms -- as well as "another 50 lookalike alarms."

That is how I tested my alarms to see if my previous testing had rendered them nonfunctional before mounting them.

Put the alarm in a sealed box and add an item that is glowing/smoking (e.g. a cigarette will do). Within a minute or two, the alarm should sound.
That would work for a smoke alarm but not for a carbon monoxide alarm. A carbon monoxide alarm needs something that produces carbon monoxide, like vehicle exhaust.

Vehicles do not produce significant amounts of carbon monoxide these days. Catalytic converters take care of that.
People used to euthanise undesirable animals caught in traps by exposing them to vehicle exhaust. Hopefully they have stopped; doing it today would be unreasonably cruel and slow.

How did you calibrate it so you know it sounds the alarm before you die from a high concentration of CO?
A quality CO sensor costs about $10..15 (Score:4, Informative)
Hence when the whole device costs in that range, you can be sure an ElCheapo $1 sensor was used. (Prices from Ebay, so YMMV.) Also, gas-flow is non-trivial, you cannot just put the sensor into a case, put some holes in that case and hope for the best. And actual testing the device is not so cheap or easy too. I expect these fails were "blind designs" were the "engineer" just read the datasheet and build the device without ever doing any real and costly testing.

in that range
You just gave a range that is larger than the cost of manufacturer of the rest of the device. Is your $15 detector crap, or does it have a quality $10 sensor with $5 of cheap electronics around it? In the case of these devices, the sensor IS the cost of the device. The rest of it is borderline free.
Also testing for a single device isn't cheap or easy because you need calibration and test equipment. That ads almost nothing to the cost when you spread it over 1000 sales on multiple different units.
To be clear you're probably right that this was some gungho idiot making some blind design and shipping it on the cheap, but you can not universally tell that from the price.

True, you need additional factors, like the number shipped and what the rest actually costs to make. Still, greed is a strong force and often people will not do essential tests even when they could have paid for them. Also note that at time of testing, they may not actually have any idea how many they will sell, unless it is a revised version of an earlier product.

Here's the thing about Chinese manufacturing. They will build to a price point and cut costs to meet the price and schedule. If you want quality you need to pay for it and closely monitor the results.

Which is good to keep in mind when buying from domestic brands, but Chinese manufacturers are increasing selling their shoddiest products directly through Amazon now. Some of these are designed directly in China with the intent of cutting costs to the minimum, which is even worse than the average cost-cutting approach used by domestic brands.
Seriously, putting much trust in brand names is silly these days, but buying a piece of critical safety equipment from TOPOLEK, or WINFI, or MODOAO or any of the assortment of identical looking and implausibly cheap sources is more than just naive.

Great points. At least with a well known brand you have some assurance of at least a minimal level of quality; plus someone to go after if it fails. As my dad said, sometime the cheaper alternative is more expensive.

Cutting costs this way is an art and not many are masters of it. You need to have an excellent understanding of the importance of all parts and steps. I have had some very optimized but still fully functional and reliable electronics components from China. I also had (rarely) utter crap. What stands out is that the good quality ones are often sold by a lot of different vendors. Still, you need to be able to evaluate quality as the buyer and have an understanding as to what price you actually need to pay or

I don't know any namebrand CO detectors because I buy them once every decade. That is my beef with Amazon, in the areas where people need guidance because they don't recognize any of the brands due to an infrequent purchase, Amazon seems to steer you to these garbage products.
But you do know name-brand stores, right? Buy from Home Depot, Walmart, etc.
Or take 10 seconds and research something that you're relying on to save your life. Never trust Amazon reviews for life-safety equipment.
Here's a freebie: the top rated CO detector by Consumer Reports is the First Alert CO615.
But don't buy it from Amazon, they are well known to have counterfeit items in their inventory, purchase from a legitimate local store.
