Our current status
When Grid Fails currently has no active affiliate partnerships and does not run paid advertising. We are not currently earning affiliate commissions through this website.
Current product links
Our product research pages may link to a manufacturer or retailer so readers can check specifications, availability and purchase terms. Current product links are ordinary links that do not earn us a commission. Featuring a product does not establish a partnership or mean that we have physically tested it.
If this changes
If we introduce commission-earning links, sponsored content or products supplied for review, we will explain the relevant relationship clearly alongside the affected content. This page will also be updated. A general disclosure page will not be used as a substitute for a disclosure where readers encounter the recommendation.
Technical content and product references
Links to technical documents help readers check the basis of an explanation. A source citation does not mean that the manufacturer endorses this website or has certified our calculator. We distinguish documented product specifications, calculations and any testing we have actually performed.
Our disclosure approach is informed by the U.S. Federal Trade Commission’s guidance on endorsements and affiliate relationships.
