Shape

While the shape of the Model O- Wireless is no different from the Model O Wireless, its much smaller size does change the way the Model O- Wireless can be gripped. Whereas the Model O Wireless lends itself well even for palm grip, most people will be inclined to claw or fingertip grip the Model O- Wireless. Much like the former, the Model O- Wireless is an ambidextrous mouse with a centered hump that slopes down gradually towards both ends. The sides are mostly straight vertically, but curved horizontally. Both the front and back barely flare out, which, coupled with the overall low profile, results in a shape that provides hardly any palm support. Compared to the Model O-, the Model O- Wireless loses the holes on the main buttons, but is identical otherwise. Overall, a non-offensive design highly suitable for smaller hands in particular.


As for grip styles, I'd say the Model O- Wireless generally suits all three main grip styles, which are palm, claw, and fingertip grip. It is a small mouse with a barely pronounced hump, which should make it generally suit medium to small hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the Model O- Wireless very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Glorious Model O- Wireless and several other ambidextrous mice. "Front height" denotes the distance between the base and main buttons.
