Shape

The shape of the GHERO Pro is very similar to, albeit not identical with the VAXEE Zygen NP-01 Wireless. The GHERO Pro is slightly smaller overall, which is mainly felt in terms of length and the rear flare, although it still is larger than the NP-01S Wireless. Much like the NP-01, the GHERO Pro fuses ergonomic and non-ergonomic design elements. The left side not being raised and the lack of a pronounced hump are traits one would expect on an ambidextrous design, yet the left and right side are clearly curved in a way that exclusively accommodates the right hand. While the main button pieces are larger compared to the NP-01, the GHERO Pro too does not feature comfort grooves, and even the side buttons are arranged similarly. In short, anyone used to the NP-01 will likely need little to no time to get accustomed to the GHERO Pro.


As for grip styles, I'd say the GHERO Pro is mostly suited for claw grip, with palm and fingertip grip being possible at least. It is a medium-sized mouse with a barely 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 GHERO Pro very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Incott GHERO Pro 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.
