Large in height, apparently under a large palm. Different pros: I took the G600 mouse because of the side buttons, it is convenient for MMO games. Convenient interface, macros are written easily and simply. Used together with the G910 keyboard they have a common software. Has cons: To be honest, the G600 mouse disappointed me, this mouse very often has a defect, namely double-clicking the LMB, I also got this one, and the “floating” defect sometimes disappears. Too big for my small palm.
