Disclosure
How PortPair Guide is funded and what our links are, as of .
Affiliate links
PortPair Guide does not currently participate in any affiliate program. No link on this site earns a commission. The "View on Plugable" and "View on CalDigit" buttons in our reviews are ordinary links to the maker's product page, and links to Apple, Plugable, CalDigit, Anker, DisplayLink and Synaptics pages are ordinary links to the documentation we cite.
If that changes, this page will name each program, the date we joined, and how affiliate links are marked. Joining a program would not change which products we review, how we score them or how we label evidence.
Sponsors, ads and free products
We have no sponsors and show no ads. We have not received free or loaned products from any company named on the site, and no company has seen or approved a review before publication.
How our reviews are made
Our reviews are research-based: researched, not hands-on tested. Each score comes from the maker's and Apple's documentation, applied to the rubric on How we review. We did not buy, borrow, measure or photograph the products, and we do not publish user reviews or star ratings. Product art is our own illustration, not a maker photo.
Why products are named
A product appears in a guide or review because its maker's documentation addresses the setup we cover. In the guides, being named is not a recommendation or a test result. In the reviews and the roundup, picks follow the published scores. Each claim carries an evidence label.
