Editorial standards
- No paid placements. We do not accept payment for a placement, a ranking or a favourable review. Where a link earns a commission, the page carrying it says so.
- No untested claims. We do not say we have tried something we have not. Prices and plan details supplied by a provider are labelled as indicative rather than presented as our own findings.
- No page for the sake of a keyword. A destination gets a page when there is something specific to say about it. That is why the site is small.
- Corrections are made in public. A factual fix is applied to the page and the update date changes with it.
