Friendly reminder: The wrist power balls are precision instruments. Before each ball is dispatched, we check that it starts properly and rotates smoothly, ensuring no quality issues exist. All packages are tightly wrapped in bubble wrap before being sent out. The balls must rotate only after successfully starting as shown in the video; at this point, your wrist strength needs to match the required level. If the ball keeps spinning after startup, contact our customer service. Another important point is that the balls must not be dropped or knocked on, as this can cause the central shaft to bend, making the ball not level, resulting in the center moving up and down and producing noise. This is clearly stated in the manual—the wrist power balls should not be dropped; if damaged, they cannot be repaired, and the bent center becomes useless, along with dents on the shell. For new customers, it is recommended to use a safety strap to hold the ball. To determine whether a ball has been dropped, simply check if the shafts at both ends are on the same horizontal line after opening it. Therefore, when learning, please remember to wear a safety strap to avoid drops. Many customers have reported that after playing for some time, the balls fail to rotate properly due to this reason. As long as the balls are not dropped and used normally for several years, there will be no problems. We do not accept returns or exchanges due to this issue—please be aware of this!
