For Different Grips
For Palm Grip Users
For typical palm grip users, the top shell provides a natural curve for your hand with a relaxed support to your palm and fingers.
For Claw Grip Users
In a typical claw grip, the mouse is held by curling your fingers together with support from your lower palm; the shape’s curved back provides an even contact to the lower palm for better grip. It also keeps your movement flexible from the front end of your palm to your fingers.
