Smartatest

Smartatest is a Swedish comparison site for smart home, safety and household products. It does not run a laboratory, and says so on every page: each verdict is reconciled from the independent tests that already exist - consumer organisations, technical labs and long-run field reports - with the weighting published and every source linked. 35 comparisons across four categories, each with a buying guide, a sortable spec table, and a dash wherever a figure is genuinely unknown rather than a number nobody measured. Twenty-nine calculators answer the question that comes before the product: how many lumens the room needs, what the lamps cost per year, which lock an insurer counts as approved. Free to read, funded by affiliate commission, and the funding is stated on every page that carries a link.
