Finding a mouse with a design similar to the M75 Air is no easy task. While some elements are shared by other designs, they are altered in such a way on the M75 Air that the end result is largely unique. For instance, the narrow front and wider rear is somewhat similar to the SteelSeries Aerox 3 at first glance, but the rear isn't as wide on the M75 Air, and the hump is centered. Most notably, the M75 Air doesn't curve inwards around the middle, but rather maintains the width of the front throughout, only widening towards the rear. The hump is perfectly centered and slopes down towards both ends, with the front sitting a bit higher than on comparable designs such as the Pulsar X2. Speaking of, much like the X2 or Pro X Superlight, the M75 Air has ledges towards the sides of the main buttons, whereas the buttons themselves are mostly level, barely showing a hint of comfort grooves. Of particular note is also the fact that, compared to other ambidextrous designs, the length of the M75 Air is above average relative to its width. Overall, a non-offensive yet unusual design, and one I didn't find too effective during use.
As for grip styles, I'd say the M75 Air is generally suited for palm and claw grip. It is a medium-sized mouse with a moderately pronounced hump, which makes it suitable for medium to large hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the M75 Air mostly comfortable in claw grip.
