Editorial standards
We explain what the evidence supports—and what it doesn't.
Our goal is not to make every product sound impressive. We examine available specifications, manufacturer documentation, pricing structures, guarantees and relevant limitations. When we have not personally tested a product, we say so. Where published information cannot support a confident conclusion, we identify that limitation rather than turn it into a sales claim.
