Shape

The shape of the Clutch GM51 Lightweight is somewhat similar to the ASUS ROG Gladius III. Much like the latter, the GM51 is a very tall mouse, but not particularly wide or long relative to its height. As with most right-handed ergonomic designs, the left side is raised compared to the right one, which further increases the already substantial height, and results in the side buttons being almost out of reach due to sitting so high. Even though the front flares out considerably, and the rear likewise flares out towards the right in particular, the mouse stays surprisingly slim, resulting in a narrower than average grip width. The hump is centered and gradually slopes down towards both ends. The main buttons feature subtle comfort grooves. Overall, a fairly unusual design that requires some getting used to.


As for grip styles, I'd say the Clutch GM51 Lightweight is mostly suited for palm and claw grip. It is a medium to large mouse with a highly pronounced hump, which makes it suit medium to large hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the Clutch GM51 Lightweight fairly comfortable in claw grip.

Dimensions

This table includes the dimensions of the MSI Clutch GM51 Lightweight 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.
