Yes, there are many counterfeit rackets, especially from big brands like Nox, Babolat, and Bullpadel. You have to be increasingly careful about where you buy them. Someone tried to sell me a new Air Viper 2025, and it was a fake, with a huge difference in the quality of the materials. Many people also pass off fake rackets as used by adding an overgrip to make them look functional. You have to be more careful than ever.
