Shape

The dimensions already give it away: The Krypton 750 is a nearly identical replica of the Razer Viper Mini. The front sits ever so slightly higher, and the Krypton 750 is ever so slightly larger, but other than that, it's very much the same thing, which has it feel the same in hand. Despite being such a small mouse, the Krypton 750 fills the hand surprisingly well owing to its tapered and mostly centered hump lending it a rather high profile. The main buttons feature deep comfort grooves, and the sides are only curved horizontally, not vertically. Overall, a tried and tested design that works well in practice.


As for grip styles, I'd say the Krypton 750 is mostly suited for claw or fingertip grip. The Krypton 750 is a small mouse, but due to the design, it should fit medium-sized hands as well. For reference, my hands are 19 cm long and 10 cm wide, and I found the Krypton 750 very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Genesis Krypton 750 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.
