## Long description

The Kensington Pro Fit Ergo Wireless Mouse features an ergonomist-approved shape with a built-in wrist rest and neutral grip that positions the right hand for improved comfort and neutral alignment. This black wireless mouse supports dual connectivity (2.4 GHz RF and Bluetooth 4.0 LE) with 128-bit AES encryption, offers quiet clicking, multiple buttons for navigation, three DPI settings and a replaceable receiver for continued use if the dongle is lost or damaged.
Advantages
The ergonomic design with integrated wrist support reduces strain by supporting and cushioning the wrist while promoting a neutral hand position. Dual wireless connectivity provides flexibility to switch between 2.4 GHz RF and Bluetooth 4.0 LE, both secured with 128-bit AES encryption. Quiet clicking and a scroll wheel enable smooth, non-disruptive operation. Three DPI settings (800/1200/1600) allow adjustment of cursor sensitivity, and a three-mode power-saving switch (2.4 GHz / Bluetooth / Off) helps extend battery life. A replaceable receiver means the mouse can be paired with a new dongle if the original is lost.
Suitable for
Office work and productivity tasks for right-handed users
Home computing where comfort and quieter operation are desired
Users who need dual connectivity (RF dongle and Bluetooth)
Environments requiring basic security with 128-bit AES encryption
