Use public evidence
Mark an item only when a page, manual, drawing, test note, or dated record answers it specifically. Marketing adjectives do not count as measurements.

Can a vent-mount listing support its fit claim?
Audit the public documentation behind any vent-mounted accessory. The result says how complete the evidence packet is—not whether the product fits, is safe, or performs as claimed.
Brand-neutral. No affiliate ranking.
Ventlings is in preproduction and has no finished mount or vehicle compatibility claim. This rubric can expose the same evidence gaps in our future documentation.
Ten questions before “fits most cars” becomes a conclusion.
Product pages often compress geometry, dimensions, installation, test conditions, and exclusions into one compatibility sentence. This scorecard separates those claims so a buyer, creator, editor, or product team can show what is public and what is still missing.
Name the gaps
The copied reviewer brief separates located evidence from missing evidence so a review can disclose uncertainty without guessing.
Keep fit product-specific
Documentation can support a comparison only after the exact vent, mount revision, installed load, location, and instructions are inside the published limits.
Stop at the boundary
The score never authenticates a source, verifies a test, overrides vehicle guidance, or certifies safety or compatibility.
Current interpretation
Mark only evidence you can actually locate.
Documentation resultNot scored
The score starts at zero. Check an item only when a public source supports it specifically.
Missing comparison prerequisites
- Supported vent geometry and exclusions
- Measured mounting-interface limits
- Vehicle-location gate
- Installation and removal procedure
A score of 10/10 still cannot establish vehicle compatibility. The rubric does not inspect the product, reproduce a test, authenticate a source, interpret a vehicle manual, or judge whether the published limits cover the exact installed configuration.
“Car vent” is not one mounting interface.
These five plain-language labels are observational shorthand, not an automotive standard. A single outlet may combine features, and naming a type does not establish compatibility.
Horizontal slats
Exposed vanes run left to right and usually tilt up or down.
Vertical slats
Exposed vanes run up and down and may move side to side.
Round or turbine
A circular outlet, often with curved vanes or a housing that rotates as a unit.
Honeycomb or fixed grid
Many small openings with no obvious individual vane to clip onto.
Recessed, flush, or hidden
The outlet or slats sit behind trim, a grille, or a narrow opening.
Transparent scoring
What the 10-point result means.
Each located disclosure earns one point. Four prerequisites—geometry and exclusions, interface limits, a vehicle-location gate, and installation/removal instructions—must all be present before the result says a product-specific comparison can start.
- 00No evidence markedThe worksheet begins at zero and makes no inference from an unchecked item.
- 01Prerequisite missingOne or more of the four comparison gates is absent, regardless of the raw point total.
- 02Comparison can startAll prerequisites are present, but fewer than eight of ten disclosures were located.
- 03Substantial packetAll prerequisites and at least eight disclosures were located. This remains a documentation result, not fit approval.
The checklist does not ask what you are reviewing.
There is no field for a product, company, vehicle, VIN, photo, name, or email. Selections remain in browser memory, are not saved to a Ventlings reservation record, and disappear when the page is reloaded. Copying creates plain text on your device. Successful copies send only the aggregate point count and result code to the site's privacy-minded analytics.
See the rule boundary Ventlings applies to its own checker.
The methodology publishes every answer set, decision rule, event boundary, and evidence limit. Ventlings still has no production-equivalent mount or confirmed vehicle fit.
