The shape of the HPC01M Pro is best described as a uniformly sized-down Logitech G Pro X Superlight. Neither the front nor back flare out much, the sides curve in only moderately, and the hump is centered and only moderately pronounced. Even the size, placement, and visual style of the side buttons is clearly reminiscent of the GPX. The most notable difference concerns the main buttons, as on the HPC01M Pro, they fully extend to the sides instead of being framed by ledges. In addition, the HPC01M Pro has a CPI button at the top, which is why the main buttons are spaced apart, unlike on the GPX. Lastly, and once again in contrast to the GPX, the main buttons feature moderately deep comfort grooves.
As for grip styles, I'd say the HPC01M Pro is generally suited for all three main grip styles: palm, claw, and fingertip grip. It is a medium-sized to small mouse with a moderately pronounced hump, which should make it generally suit most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the HPC01M Pro very comfortable in claw grip.
Dimensions
This table includes the dimensions of the Incott HPC01M Pro 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.
