Shape

It is fair to say that the Terra Pro is a near-exact copy of the Logitech G403/G703 shape. Most of the dimensions are an exact match, and even minute details such as the way the main buttons are curved, how wide the ledges next to the main buttons are, or how the rear is angled up, have been recreated closely. Even the positioning of the scroll wheel and the size of the side buttons are identical. The only notable difference is the bridge between the main buttons, which only extends towards the front. In short, anyone who ever used the G403/G703 shape will feel right at home.


As for grip styles, I'd say the Terra Pro is generally suited for palm and claw grip. It is a medium to large-sized mouse with a fairly pronounced hump, which should make it generally suit medium to large hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Terra Pro very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Teevolution Terra 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.
