Unbranded Red and white smoke alarm review

Product alert

Don't Buy this smoke alarm – it failed to detect smoke in all eight of our fire tests

When set the task of detecting smoke from fires fuelled by wood, plastics, cotton and solvents, this unbranded and unreliable product failed to sound in all of our fire tests.

It’s one of the most unresponsive and potentially dangerous alarms we’ve seen and in our tests, we found it unable to reliably detect smoke and that’s why we’ve made it a Don’t Buy.

This terrifyingly unreliable smoke alarm failed every one of our eight smoke detection tests. That’s why we’ve made it a Don’t Buy and are warning you about it. We bought this alarm from eBay but we’ve also seen listings for it on Wish. It’s white and circular with a red circle in the middle. The packaging is dark red and the only text on the box is in Chinese as are the user instructions. If you’re in the market for a new smoke alarm, don’t be tempted by this product - it’s one of the most dangerous products we’ve tested and that’s why we’ve made it a Don’t Buy.
