Unbranded WiFi smoke alarm review
Product alert
Don't Buy this smoke alarm – it failed to detect smoke in four of our eight 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 each fire scenario. 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 unbranded smoke alarm that we purchased from a seller on eBay and was shipped from China is among the most dangerous products we’ve tested. You might also find it listed on AliExpress and Wish. One of the two samples that we tested failed to sound at all in three of our four smoke tests, simply failing to do the one job it was designed to do. And when it did sound, it took far too long to raise the alarm. The other sample that we tested failed to sound in one of our tests and was slower than many models in two other tests. So, with a test pass record of sounding in just four of our eight tests, this is one of the more obvious Don’t Buys for Which? to warn you about.
