Shape

The Hati-S Ultra 8K matches the original Hati-S exactly. Compared to the Hati-S2 8K, the Hati-S Ultra 8K is longer and has a higher hump, with the other dimensions being an exact match. The hump is mostly centered and slopes down rapidly, the front and back flare out to a similar and moderate degree, and the main buttons have moderately deep comfort grooves. In addition, the base is narrower at the front, resulting in small ledges next to the main buttons. Aesthetically, the presence of hexagonal holes across the entire shell is immediately noticeable, though these are "filled" in spots that are considered finger contact points, such as the sides and a small portion of the main buttons, right towards the front.

Compared to earlier revisions of the Hati-S, the sensor has been moved forward. That said, the shift is rather miniscule, barely altering one's wrist motion arc as a result.


As for grip styles, I'd say the Hati-S Ultra 8K is mainly suited for claw grip. 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-S Ultra 8K perfectly comfortable in claw grip.

Dimensions

This table includes the dimensions of the G-Wolves Hati-S Ultra 8K 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. For a full list of all measurements taken, please refer to this sheet compiled by an esteemed community member.
