1. Nowadays, you can scan the QR code for genuine products. This identification method is simple and effective.

2. Is there any anti-counterfeiting? Products released after 2008 all have anti-counterfeiting on the handle. The serial number can be checked online or by phone.

3. Products before 2008 do not have anti-counterfeiting serial numbers. They can only be queried based on the steel engraved number. The steel engraved number and the agent's number can be queried together.

4. Intuitive experience judgment method. This requires a certain amount of experience. Is the balance point in the middle of the racket head in the middle? If it is false, it will be a little biased and obvious. There is also the bottom cover. Check whether the victory logo is rough or not. The most important thing is to try it out before you know how it feels.
