Honeywell XC70 review

£19.00 Typical price

Test resultShow Context

The Honeywell XC70 carbon monoxide alarm comes with a sealed seven-year battery and this means that for the time that you own it, you won't need to change the battery.

We tested it back in 2018 to find out. Read on for the full results of our tests.
