Button customization is one of the defining strengths. Reviews emphasize adjustable actuation, haptic feedback strength, rapid trigger behavior, independent left/right tuning, remapping, and G Hub configuration.
Synapse and Synapse Web are repeatedly cited for remapping and control over the available buttons. Reviewers present customization as thorough rather than bare-bones.
Button customization is well supported through G Hub, including remapping, G-Shift, switch behavior, and programmable functions. The limitation is the small number of physical buttons available to customize.
The mouse supports button remapping and related Synapse controls, but customization is limited by the simple physical button layout and bottom-mounted DPI control.
