Typical price


Ei Electronics’ Ei207 Carbon Monoxide Alarm comes with a market-leading 10-year lifetime, which is longer than the ususal six or seven years that most carbon monoxide alarms last. This longevity will cost a little extra, but is it money well spent? We tested just how effective it is at detecting poisonous carbon monoxide, and how quickly and clearly it sounds the alarm, in our test tab to find out.
Is it worth your money?
Or is it a waste of cash?
