Commercial disclosure

Affiliate links should be obvious.

SpaceFit Lab uses merchant links to help readers verify named products after completing the measurement guidance.

Amazon Associate disclosure

As an Amazon Associate I earn from qualifying purchases.

Amazon links marked (paid link) may earn SpaceFit Lab a commission if a reader makes a qualifying purchase, at no additional cost to the reader.

What commission does not buy

Payment does not turn manufacturer claims into our test results. Rankings and layout guidance must still state their evidence level, limitations and relevant measurements. We do not offer cashback, rewards or purchase incentives for using an affiliate link.

Evidence remains separate

No product is labeled hands-on tested unless that evidence is explicitly documented. Product availability, seller terms and affiliate eligibility are rechecked separately from the editorial decision.
