The scroll is loose and makes sounds when moving the mouse quickly.
Troubleshooting / 2023-08-03
The wheel may shift slightly as to keep good level of flexibility when it is rolling, but it should not affect the function and performance. And also, the mouse wheel worn out time by time.
If your mouse is still within warranty period, and you think the sound/losseness is at an unreasonal level, or even impacts the performance, please contact us (ZOWIE website/Support/Contact/RMA) for further assistance.
