To put it as succinctly as possible, the shape of the MoshPit WHM-01 is virtually identical to the Logitech G Pro Wireless. The MoshPit flares out a bit more at the front and back, however, and ends up being wider and plain bigger overall. The side curvature is more pronounced than on the Pro Wireless as well, resulting in a decisively different grip feel, and unlike on the Logitech Pro, the main buttons extend across the entire width. Other than that, the MoshPit WHM-01 too features the centered hump that gradually slopes down toward both ends, and lacks any sort of aggressive curves. Overall, a tried and tested shape that works well in practice. The honeycomb pattern extends to the top and the bottom, but not the sides.
As for grip styles, I'd say the MoshPit WHM-01 is generally suited for all three main grip styles: palm, claw, and fingertip grip. It's a medium-sized mouse with a moderately pronounced hump, which makes it suitable for most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the MoshPit WHM-01 very comfortable in claw grip.
Dimensions
This table includes the dimensions of the LTC MoshPit WHM-01 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.
