Look Into Products: UK Amazon picks with the claim checked
One honest pick per job, from what Britain is actually buying on Amazon UK. We price the listing on the day, check the maker's headline claim against what the maker actually publishes, and work out what the thing costs to run.
What "the claim checked" means
A maker's headline number is only useful if the test behind it is published. Repeatedly it is not: none of the 32 bestselling home printers on Amazon UK states a cost per page, none of the 25 bestselling e-reader listings says how its battery claim was measured, and only Amazon's own streaming devices state a security update period. Where the condition is missing, we say so and derive the figure ourselves from the maker's own specification, showing the arithmetic.
