What we evaluate
We compare current manufacturer documentation for dimensions, anchoring, materials, controls, drainage, warranty and operating limitations. We favor model-specific evidence over generic category claims.
What we do not claim
We do not imply hands-on testing where none occurred, calculate structural capacity from marketing dimensions, or replace local permit, engineering or installer review.
Updates and corrections
Pages show a review date. Product specifications and program terms change, so readers should verify the exact current model. Corrections can be sent to hello@opstudio.dev.
