After using the Fan Zhendong double-code gold tag blade from 3T Ping Pong Shop for about two months, I can confidently confirm that it is 100% authentic, and the difference from the commercial Butterfly Fan Zhendong ALC is immediately clear. The sensations are on a completely different level, the blade offers a unique blend of soft rebound, crisp stiffness, and precise feedback, making it feel far more alive in the hand. What impressed me most is how naturally it shifts between explosiveness in attacking strokes and high control in the short game; when you want power, it delivers effortlessly, but when you need delicate touch, it responds with impressive stability and feel. Overall, it doesn’t just feel better than the commercial version, it feels like a true professional tool rather than a mass-produced product.
