Shape

The shape of the Naos-M is very similar to that of the Zowie S2. The Naos-M ends up being slightly smaller overall, but the general curvature is all but identical. Whereas the front is rather narrow, the back is quite wide, which, along with the rear-positioned hump that goes into a gradual slope, creates ample space to rest one's palm on. The sides curve inwards horizontally to a moderate degree, but are mostly straight vertically. Compared to the S2, the front sits a bit higher, and the main buttons have very subtle comfort grooves. Unlike the Mira-M/S, the Naos-M does without the honeycomb pattern on the sides. Similarly to how Glorious does it on their mice, the holes only cover the top and half of the main buttons, along with the bottom. Personally, I still prefer solid sides, although I didn't mind the way the holes on the sides were done on the Mira-M/S.


As for grip styles, I'd say the Naos-M mostly suits claw and fingertip grip, though palm grip is possible as well at least. It's a medium-sized mouse with a moderately pronounced and rear-positioned hump, which should make it suitable for most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Naos-M very comfortable in claw grip.

Dimensions

This table includes the dimensions of the HK Gaming Naos-M and several other ambidextrous mice, along with a right-handed ergonomic one. "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.
