I work on and game on a large LCD so I like mice with lots of sensitivity so I can use smaller hand movements for play and navigation. For most of us, the normal mouse form factor is just fine, but for some with hand injuries or the need to be different the Jelfin mouse may be perfect.
The mouse is a round ball style device covered in gel. The round design conforms to your hand and the gel adds more comfort. Jelfin says that the mouse is like a stress ball that can be squeezed. Sensitivity is 1000 dpi.
The mouse ship sin a metal box that can be reused for storage. Available colors include red, blue, yellow, green, and pink. The Jelfin mouse is available now for $34.95 and works with Mac and windows computers.
