It has an ergonomic right-handed design, with a plethora of customizable buttons and 14 RGB zones.

Unfortunately, Razer Synapse 3 isn't available on macOS. While this mouse will work with default button configurations on Mac out-of-the-box, if you want to customize them, you'll have to make the changes on a Windows-based PC and save them to the mouse.
