ZOWIE FK1+-B RED V2 Mouse for Esports

Is there a good way to wrap around or bundle up the cable that prevents internal breakage while it's in storage?

The cursor on the screen shakes and starts moving on its own without touching the mouse or with my hand just resting on it.

The mouse has been working intermittently. Applying force against the mousepad seems to get it back in working order, and the issue does seem slightly diminished at higher DPI settings.

The sensor has suddenly become less accurate in game at 1600 dpi. The mouse moves like 400 dpi. What should I do?
