Inspired by nature. Visually, the vertical mouse stands out with its shape mimicking the human hand, making it a true unique model. The ergonomic design of the CSL vertical mouse protects your wrist from unnatural strain. The arm can adopt a neutral position, keeping the wrist relaxed. This helps prevent mouse or tennis elbow (RSI syndrome), allowing you to work comfortably even after hours. The wireless control via Bluetooth also contributes to this. No cables interfere with your arm movements, allowing you to move the mouse freely across the table.
