Shape

According to Glorious, the Model O 2 Mini Wireless is a Model O 2 Wireless, uniformly scaled down by 6%. Accordingly, all the changes made to the Model O 2 Wireless compared to the original Model O carry over to the Model O 2 Mini Wireless. 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 Mini 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 Mini Wireless handles virtually the same in practice as the Model O- Wireless.


As for grip styles, I'd say the Model O 2 Mini Wireless is mostly suited for claw and fingertip grip. It is a small mouse with a barely pronounced hump, which makes it more suitable for medium to small hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the Model O 2 Mini Wireless very comfortable in claw grip.
