FUNDING / TRANSPARENCY

Affiliate disclosure.

How paid links support the publication—and what they do not change about the research.

REQUIRED DISCLOSURE

As an Amazon Associate I earn from qualifying purchases.

1. How affiliate links work

Some links from FitCheck Lab to Amazon are special affiliate links. If you follow one and make a qualifying purchase, Amazon may pay FitCheck Lab a commission. FitCheck Lab does not add a separate charge to your order. Amazon and the seller set the price and transaction terms.

2. How paid links are labeled

Amazon shopping links are marked with language such as "paid link" or a nearby Amazon Associate disclosure. The disclosure appears near the shopping action as well as in the site footer so readers do not need to find this page before understanding the relationship.

3. Editorial independence

Compatibility conclusions are based on the source hierarchy described in our research method. Commission potential does not turn an unverified fit into a confirmed fit. A page may link to a broad Amazon search because individual listings and sellers change.

4. No Amazon endorsement

Participation in the Amazon Associates Program does not mean Amazon owns, sponsors or endorses FitCheck Lab. Amazon and the Amazon logo are trademarks of Amazon.com, Inc. or its affiliates.

5. Prices, sellers and fit

FitCheck Lab does not display live Amazon prices. Confirm current price, seller, shipping, return terms and exact-model compatibility on Amazon before purchasing. A marketplace title is not treated as primary compatibility evidence.
