Frequently Asked Questions
Every recommendation comes from verified vehicle-compatibility and scanner-specification data in our catalog, filtered and ranked by a fixed, deterministic set of rules — never a sponsored placement, and never an AI guess.
No — we verify publicly available specification and compatibility data rather than performing our own product testing. Each scanner page discloses what has and has not been verified.
We participate in the Amazon Associates program and earn a commission on qualifying purchases made through our links, at no extra cost to you.
We only display a specification once it has been verified from a reliable source. A field reading “Not yet verified” means we don’t yet have a confirmed answer — we never guess.
