Why FitCheck Lab exists
Appliance accessory listings often compress several incompatible model families into one product name. FitCheck Lab turns scattered manufacturer records into model-level compatibility guidance, with a visible date and an explicit boundary around what remains unknown.
Editorial standard
- Read the exact model number before relying on a family name.
- Prefer current US manufacturer records and manuals.
- Separate confirmed fits, explicit exclusions and unresolved cases.
- Identify sources and show when the research was last checked.
- Do not borrow review photos or imply hands-on use that did not happen.
The full evidence hierarchy is published on the methodology page.
Funding
FitCheck Lab is supported by affiliate commissions from qualifying Amazon purchases. Paid links are disclosed near the link. Funding does not change the evidence threshold or create a relationship with the manufacturers discussed. Read the full affiliate disclosure.
Corrections and updates
Manufacturer pages and part catalogs change. When reliable evidence shows that a compatibility statement is incomplete or outdated, we review the source, revise the page and update its verification date. Correction requests should include the affected URL, exact model or part number, and a primary-source link or document.

Brand independence
FitCheck Lab is an independent publication. It is not owned, sponsored or authorized by Amazon, Ninja, KitchenAid, Breville or another brand referenced in the research. Product names and trademarks belong to their respective owners.
