Claims Checked
Product listings say a lot of things that nobody has to prove. This page gathers every place on Look Into where we read listings and maker documents side by side and wrote down where the claims hold, fall short or go missing. It updates itself when a new guide with a listing check is published.
How we do it: we open the listings and the maker's own specification, read them on a stated date, and quote the figure each one gives. We have not lab-tested these products. Where a number is missing, we say so rather than estimate it. Our method · How we make money
92 pages with a claims check · 87 of them inside buying guides and comparisons · at least 1,582 listings and product claims read, counting only sections whose heading gives a number.
