UnbrandedWiFi smoke alarm

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.
