Kensington Pro Fit Ergo Vertical Wireless Mouse (Black)

Vertical mouse features a contoured, 46.7-degree slope that positions your wrist in a handshake position to eliminate soft tissue compression. Extended lip provides complete support for smoother, larger muscle group movement. Six-button design offers more control directly at your fingertips. Plug-and-play technology requires you to simply plug in the nano receiver for wireless connectivity up to 65'. Low-battery indicator lets you know when it's time to change the battery to prevent unexpected runout. Long battery life uses just one AA battery to provide up to a year of use. Nano receiver storage offers a convenient location to keep the receiver when note in use.
