Tech reliability
Which brands make the most reliable technology?
The year is 2024. Telephones scan your face to authorise payments. Headphones make 3D maps of your ears to optimise sound. And yet, what we desire most is a device that does the basics well for a long time.
About our survey
In our annual reliability and satisfaction survey, consumers tell us about faults that have left a product they own unusable or mean they’ve had to change how they use it. We also ask them how satisfied they are with the appliance. We use their data to produce our predicted reliability and owner satisfaction scores.
We use a statistical test to rate the relative performance of each brand. Compared to data we have for all products (of the same type) in the survey, we rate each brand with highest, high, average, low or lowest reliability and satisfaction. You can compare the rating of different brands for the same product type (for example, the reliability rating for Miele and Haier washing machines), but you can’t compare the results for different product types (for example, satisfaction of LG TVs and Samsung phones).
We analyse brands that get at least 30 responses in our survey. That means there are some brands we can’t analyse because we don’t have enough data.
