Topolek GEHS007AW Carbon Monoxide Alarm review

£14.99
Launched Reviewed

Product alert

Don't Buy this carbon monoxide (CO) alarm - it's unreliable at detecting carbon monoxide and is unsafe

We tested this alarm and were concerned to see that it regularly failed to detect carbon monoxide (CO) in our tests. This means that if you owned one, you wouldn't be able to trust it to sound if there was a build-up of CO in your home.

This product failed to sound in 15 of our CO tests. Best Buy carbon monoxide alarms need to sound in every single one of our tests. Our lab tests are ongoing and we will update this warning when they are complete.

The Topolek carbon monoxide (CO) alarm is a Don’t Buy. In our lab tests it regularly failed to detect the killer gas. If you have one in your home, you should replace it with a Best Buy. To become a Which? Best Buy, carbon monoxide alarms need to pass all 33 of the CO tests we set them.
