Shape

Even though slightly different in some places, the Feather essentially is a near-exact copy of the Zowie FK2 shape: low-profile, a wide front, centered hump that gradually slopes down towards both ends, and horizontally curved-in sides. The differences are miniscule: Aside from the main buttons, which feature minor comfort grooves, the sides differ the most. Essentially, they are segmented into two parts: The upper part has holes and is white, whereas the lower part, where the fingers and thumb typically reside, is solid and has a dotted texture. Though hardly original, it is a tried and tested shape that works very well in practice.


As for grip styles, I'd say the Feather mostly suits claw and fingertip grip. It's a medium-sized, low-profile mouse, which should make it generally suit most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Feather very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Ducky Feather 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.
