1, look at the overall appearance.

The original YY badminton racket shaft and racket frame are bright and flat, and English characters, icons and other symbols are clear and tidy; However, the fake badminton racket is not as good as the original badminton racket in all aspects, especially the shield-shaped PBSI logo on the handle, which is far from being clearly visible. In addition, the factory number (commonly known as steel number) is engraved on the symmetrical plane or the racket shaft of the original feather racket handle PBSI logo, and the newer original feather racket handle and racket shaft adopt the advanced photoetching steel number which is not easy to forge (double steel number: the number on the racket shaft is the product serial number, and each racket is different; The number on the handle is the product batch number, which is the same as that of the same batch of products); Most fake feather bats don't have factory numbers.

2, look at the line hole colloidal particles

After the original YY badminton racket is put into the racket frame, the inner end is not cut, and basically different positions use different sizes of rubber particles. Rubber particles in the threaded hole are injected by a mold, and the ends are chamfered at 30-45 degrees. At the position where the middle and high-grade racket frame crosses the hard horizontal line, the rubber particles in the thread holes inside the badminton racket frame are V-shaped; However, the rubber particles of the fake feather racket are usually cut after being installed, and the rubber particles of the same size are basically used in different positions, and the ends of the rubber particles are flat without chamfering.

3, look at the handle rubber

The original YY feather racket handle rubber is thin and soft, and it is evenly wound, flat and stable; The rubber of the handle of the fake badminton racket is thick and slippery, which is easy to loosen and slip, and will soon break after use.

4. Look at the back cover of the racket handle

The colors around the Japanese letters on the back cover of the original YY feather bat handle are uniform; On the other hand, the Japanese letters on the back cover of the fake feather racket handle can see long white marks, which are rough.

5. Look at the racket cover

YY original feather suit has various styles, and different agents have different feather suits, which are soft to the touch. Some YY or Yonex trademarks on the outside of the pat sleeve are also embroidered by computer; But there are differences between fake badminton rackets and various types of rackets.
