Shape

The shape of the M65 RGB Ultra hasn't been altered in any meaningful way compared to its predecessors. Geometrically, it is still closest to a diamond shape, being widest in the middle and narrower towards the back and front, with a mostly centered and relatively low-sitting hump. The left side extends into a thumb rest, albeit without widening the mouse much. A large part of the frame is made out of aluminium, which the other plastic parts attach to. Despite being a right-handed ergonomic design, the left side is barely raised, which has the M65 RGB Ultra feel more like an ambidextrous shape in practice. Overall, a tried and tested shape that is quite comfortable in practice, although I wouldn't describe it as wieldy.


As for grip styles, I'd say the M65 RGB Ultra is mostly suited for palm and claw grip. It is a wide, medium-sized mouse with a moderately pronounced hump, which makes it suitable for medium to larger hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the M65 RGB Ultra fairly comfortable in claw grip.
