CSL ergonomic mouse, corded, optical vertical left-handed mouse, against mouse arm/tennis arm

The vertical design of CSL's ergonomic left-handed mouse enables a neutral hand position during use and offers high comfort. This leaves the arm in an untwisted and neutral position when working on the PC or notebook, avoiding the twisted posture common with conventional mice.

The vertical left-handed mouse allows you to place your arms relaxed on the table while maintaining a natural hand position, with palms pointing towards each other as if shaking hands. This posture relieves the hand and is further supported by the ergonomic design and non-slip surface of the mouse. The mouse features both right and left buttons, as well as back and forward buttons for comfortable web browsing, and a DPI selector switch that allows you to flexibly switch between different sampling rates during operation.
