Faulty smoke alarms are continuing to be sold online - something that could be putting lives at risk.
Consumer watchdog Which? bought alarms and carbon monoxide detectors on the internet that then failed basic safety tests.
Even after they were found not to work ITV Meridian was able to buy two of the faulty products from an online retailer. We tried to contact the manufacturers but were unable to find a way to do so.
In a statement the eBay said the items have been removed and that they have taken enforcement action against the sellers.
Smoke can fill a room in seconds. Fire officers have been in a training house which is used to teach firefighters how to respond when people overcome by smoke.
West Sussex Fire & Rescue Service carry out safety tests in the home and fit free alarms.
But some alarms don't work because they are fitted badly, with others being sold online despite being faulty.
West Sussex Fire and Rescue say the importance of having a fire alarm that works can't be overrated.
The advice is to check your alarms, and test them every week.
