The ergonomic mouse avoids forearm twisting, has adjustable pointer speed, improved thumb rest, two thumb buttons, and a new bottom thumb button. The Evoluent VerticalMouse 4 (VM4R) is compatible with Windows 7, 8, 10, and 11, Mac OS X, and Linux. It requires a USB connection and has basic functionality on all systems without a driver, though drivers are available for downloading to program the 6 buttons. The mouse is not compatible with PS/2 adapters and while it may work with some KVM switches, compatibility is not guaranteed. |
