Shape

While the ZPW Max clearly takes the Z2 as its template, it incorporates many elements of the SteelSeries Prime shape, to where it ends up being almost the same. Similarities can be found in the front, which is similarly narrow, the back, which is similarly wide, the degree to which the left side is raised, and the way the left side curves in. At the same time, the ZWP Max retains the hump curvature of the Z2, with its centered hump sloping down gradually towards both ends, whereas the Prime has its hump positioned slightly towards the front, resulting in a steeper decline towards the front. On the Prime, the rear also appears more angular, whereas the ZPW Max features the same rounded shape as the Z2. Much like on the Prime, the main buttons are framed by ledges, and the aesthetic of the main buttons is clearly matched otherwise as well. Overall, the ZPW Max is reasonably close to the Prime, but not an exact clone, neither in shape nor size.


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

Dimensions

This table includes the dimensions of the Zaopin ZPW Max and several other right-handed ergonomic 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.


Below are some comparison shots with each of the measured mice:
