Six places fitment
goes wrong first.
Every category has its own failure modes. We compare the details that cost time, shipping and second installs—not just weave and price.

03 / Evidence over claims
A grade you
can audit.

Read the full methodology ↗Independently documented
Consistent independent evidence beyond the seller listing.
Seller claimed
Compatibility is published by the seller but not independently confirmed.
Conflict or unknown
Claims disagree, exclusions are unclear, or evidence is incomplete.
04 / Compare smarter
Same look.
Very different risk.
