X-Sense CO03D review

Product alert

Don't Buy this carbon monoxide (CO) alarm – it failed to sound in one of our carbon monoxide detection tests

The X-Sense CO03D carbon monoxide alarm failed to sound when challenged to detect a catastrophically high concentration of carbon monoxide and all three samples we tested failed the test.

The CO03D passed all of our other gas detection tests, but based on the failures we saw in our lab, we have to make the product a Don’t Buy.

Expert review

The X-Sense CO03D carbon monoxide alarm failed to sound in one of our carbon monoxide tests when we tested it in 2018. Because of the safety concerns we have based on the gas detection failure in our tests, we've made this X-Sense alarm a Don't Buy. This product failed to sound when in the presence of a catastrophic concentration of carbon monoxide and all three of the samples of alarm we tested failed in the same way.
