This alarm failed to detect carbon monoxide (CO) in our tests, which makes it dangerous. High levels of CO went repeatedly undetected. When tested with a super-high concentration of the gas, it did work initially, but then failed to continue to work afterwards. Also, it’s nowhere near loud enough. We recorded just 65 and 67 decibels (dB) when it should have sounded at 85dB to start with, then at least 82dB after four minutes. Also, the instructions are dangerously misleading, advising users not to install it in a kitchen, where in many UK homes you’ll find a gas boiler and where you would need a CO alarm. It’s an altogether unsafe product, so it’s clearly a Don’t Buy.
