Find the exact racket specification
Match the full name, version and options to the manufacturer's documentation.
Separate the names
A brand is the name used to market a product; a range groups products; the full model name identifies a model within that range. Keep every suffix and generation marker. A similar name or colour does not establish that two rackets share a specification.
Find official documentation
Start on the manufacturer's website and search the full model name or product code. Open the result itself. The Yonex ASTROX 77 PLAY page, for example, gives the product code AX77-PL. Record the page address and consultation date so you can find the same document again.
Match five details
Use the same five checks for every racket:
- Brand, range and full model name.
- Manufacturer's product code, if published.
- Version, generation and any suffix.
- Weight class and handle size for the version concerned.
- Region covered by the document and its source address.
Compare the markings available on the racket or packaging with the document. The VICTOR DriveX F T page lists separate weight and handle combinations. Keep each combination together; do not invent a variant by mixing options.
Leave gaps visible
If a code, version or option is absent, write “unconfirmed”. Keep documents from different regions separate until the manufacturer confirms which applies. A missing page does not establish that a product is fake or discontinued. Ask the manufacturer's local contact for documentation rather than substituting a neighbouring model.
Separate the model from the offer
Ask the seller to confirm the exact variant supplied and any fitted strings, added grip or accessories. A manufacturer specification does not describe that seller's offer. It does not authenticate an individual racket or guarantee that it suits your play. These checks provide neither a brand ranking nor a buying recommendation.
