Shape
The shape of the Logitech G PRO X Superlight wireless mouse did not change at all from its predecessor the Logitech G Pro wireless. The Superlight uses the same shell, therefore if you had previously owned a G Pro wireless you will feel right at home in terms of shape.
The shell has one of the safest shapes on the market when it comes to top-tier mice, minimizing risks as much as possible. What this means for the Logitech G PRO X Superlight is that the shape will never be the most comfortable for anybody, but it will never offend anyone either.
