Shape

The Model O 2 Wireless differs from the Model O Wireless both on a visual and geometrical level. Aesthetically, the most noticeable change are the holes, which are now circular instead of hexagonal, but still cover the back and bottom of the mouse. The bearded man, which is Glorious's brand logo, is no longer printed on the left side of the mouse, and the main buttons have been redesigned entirely. The buttons no longer extend across the entire width, and instead are framed by lateral ledges, though the actual curvature of the buttons is unchanged, including the moderately deep comfort grooves. Geometrically, the main buttons sit slightly lower now compared to the Model O Wireless. Height along with front and back width are virtually the same, but the Model O 2 Wireless is slightly wider around the middle, as the sides no longer curve in as much, resulting in a smaller vertical angle. Overall, the changes are quite subtle, and the Model O 2 Wireless handles virtually the same in practice.


As for grip styles, I'd say the Model O 2 Wireless is generally suited for all three main grip styles, which are palm, claw, and fingertip grip. It is a large mouse with a barely pronounced hump, which makes it suit medium to larger hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the Model O 2 Wireless very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Glorious Model O 2 Wireless and several other ambidextrous mice. "Front height" denotes the distance between the base and main buttons. Measurements with two decimals have been taken with a caliper, while those with one decimal have been taken with a ruler. For a full list of all measurements taken, please refer to this sheet compiled by an esteemed community member.
