Shape

This shape has been around for several years at this point, but it still is a rather unique and unusual design. The most peculiar design trait is surely the pronounced ring finger rest (or pinky rest, depending on your grip) on the right side. This finger rest is contoured in a way that has the pinky neatly fit to the right as well. Additionally, the left side extends a bit further, providing a small thumb rest area as well. Clearly, this shape is intended to be used in palm grip, yet the hump is only mildly pronounced and extends almost fully flat across the width. The left side isn't raised much, either. Another peculiarity is the sensor's position. No matter which grip is used, the sensor will always sit a fair bit lower than on most other mice. This is mostly something that requires some good getting used to and not an inherent flaw or anything of the like, though.


As for grip styles, I'd say the Naos Pro is mostly suited for palm grip, with claw grip being possible at least. It is a medium-sized but wide mouse with a mildly pronounced hump, which should make it suit medium to large hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the Naos Pro quite comfortable in claw grip.

Dimensions

This table includes the dimensions of the Mionix Naos 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.
