Shape

At first glance, one might mistake the Hati-R 8K for an ambidextrous design, though that is not the case. Ever so subtly, the left side is raised by a small degree, and the right side reaches farther to the front than the left side does. In practice, these traits are too miniscule to actually be felt in any way, given how the Hati-R 8K is primarily intended to be used in fingertip grip, though claw grip may also be possible for those with very small hands. The latter possibility is facilitated by the pronounced hump being located towards the back, which is tapered instead of extending across the entire width like on the HSK Pro. The Hati-R 8K retains its width across the front and middle, where it is widest, and only narrows towards the rear. Around the grip area, the Hati-R 8K is wider than the HSK Pro, lending itself better to larger hands, though by gripping it more towards the back, one has some control over the grip width. The main buttons feature fairly deep comfort grooves, though these do not matter much for fingertip grip anyway. While not necessarily groundbreaking, the shape of the Hati-R 8K is rather unique and novel for a fingertip grip design. Very small hexagonal holes are found on the sides, but not the top of the mouse.


As for grip styles, I'd say the Hati-R 8K is mainly suited for fingertip grip, though claw grip may be possible for those with smaller hands. It is a small mouse with a pronounced hump, which should make it generally suitable for most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Hati-R 8K perfectly comfortable in fingertip grip.

Dimensions

This table includes the dimensions of the G-Wolves Hati-R 8K 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.
