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.”
