Affiliate relationships
When Grid Fails uses affiliate links on some pages. If you click an affiliate link and make a qualifying purchase, we may earn a commission at no extra cost to you. Not every external link is an affiliate link.
We place a short disclosure near the beginning of articles that may contain affiliate links. This page provides additional detail and does not replace the disclosure shown with the recommendation.
How product links work
Affiliate links may contain tracking parameters or redirect through an affiliate network so a merchant can attribute a purchase to this website. The merchant or network may process referral and technical information under its own privacy policy. Prices, availability, promotions and eligibility can change; verify the final terms on the seller’s website before purchasing.
Editorial approach
Compensation does not guarantee a positive recommendation or determine the technical conclusions in our guides. We compare products using published specifications, documented features, source quality and fit for a stated use case. We do not claim hands-on testing unless a page explicitly states what was tested and how.
Featuring or linking to a product does not mean the manufacturer endorses When Grid Fails, our calculator or our conclusions. Technical source links may be non-affiliate references.
Sponsored or supplied products
If content is sponsored or a product is supplied for review, we will disclose that relationship clearly with the affected content. Affiliate commissions are separate from any such arrangement.
Questions
Our disclosure approach follows the U.S. Federal Trade Commission’s guidance on endorsements and affiliate relationships. Questions about a link or relationship can be sent to contact@whengridfails.com; please include the page URL.
