Revolution Hurricane Rotating Anal Vibe - Teal

What create the rotation or vibration effect is the big ball where is located the charging port. The tip almost don't move. The charging port is not available after that the ball spin. The plastic of that toys is probably the worst cheapest quality that I ever had.
It's my first toy from NS Novelties and there's no chance that I buy a other toys from them the plastic/ silicone rubber is the worst cheapest quality that I ever saw
