Our search for the source of the dodgy alarms led us to a factory in China. We’ve seen documents stating that one alarm made there – which is identical in appearance to the models that failed our tests and was offered for sale to us – had passed the EU safety tests.
But on closer inspection, the claimed legitimacy becomes murkier. The documents show only four days between the start and end of testing, when it actually takes at least three months to pass the EU safety tests.Amazon and Ebay respond
Amazon told us: ‘The products in question have been removed from sale while we conduct a review of them.’ Ebay told us that customer safety is its number one priority, that it’s working with the alarm sellers to ensure its customers are informed, and that it works with Trading Standards to ensure listings comply with the law.
The importers of the Binwo and Mudder alarms didn’t respond to our offer to comment. ATZ Essentials, the seller of the ATZ Saviour alarm, told us it’s removed the alarm from sale, it apologises for any inconvenience and has offered a refund for alarms bought through Amazon.Recommended Monoxide AlarmsKidde Single Carbon Monoxide Alarm.- £19.99 - ArgosLifesaver Carbon Monoxide Alarm - £16.99 - HomebaseFireAngel LED Display Carbon Monoxide Detector - £21 - B&Q
