About our survey

We asked our members about products they’d bought new since 1 January 2013. We wanted to know the brand, the year it was bought and whether it had ever needed repair. We also asked respondents if they were satisfied with their product. Our thanks to all who participated.

We only analyse brands that got 30 or more responses in a category. For each brand, we calculate our reliability score as the percentage of its products that have never needed repair. Satisfaction is the percent of owners who were “very satisfied” with their product (scored 8, 9 or 10 on a 0-10 scale).

Where we haven’t re-surveyed a particular product, we’ve included the reliability data from our 2016 and 2017 surveys.
