LOGITECH SOURIS Ergo S Advanced Wireless Trackball – GRAPHITE – 2.4GHZ/BT – N/A – EMEA28-935 – EMEA

Adjustable Tilt Angle: Features a unique, hinged base that allows the user to customize the trackball’s angle from $\mathbf{0^{\circ}}$ to $\mathbf{20^{\circ}}$ (and up to $30^{\circ}$ with an accessory wedge). This adjustable tilt is designed to instantly improve wrist and forearm posture.

Reduced Strain: The stationary trackball design minimizes arm, wrist, and hand movement, resulting in up to 20% less muscle fatigue in the hand, wrist, and forearm compared to a regular mouse.

Contoured Design: The sculpted shape provides full palm and finger support, while a soft, rubber-coated top offers a comfortable grip for long hours of work.

Space-Saving: Since the trackball remains stationary, it is ideal for tight workspaces or busy desks.

Trackball: The thumb-operated ball controls the cursor movement, providing excellent tracking and accuracy.

Precision Mode Button (DPI): A dedicated button next to the ball lets you instantly switch between two tracking speeds/resolutions for quick movement or fine, pixel-level precision work.

Scroll Wheel: Features a Precision Scroll Wheel that includes a tilt function for horizontal scrolling (e.g., navigating lengthy spreadsheets).

Customizable Buttons: Includes eight buttons in total, with up to six programmable buttons that can be customized with app-specific shortcuts using the Logi Options+ software.

Dual Connectivity: Connects wirelessly via two secure options:

• Logitech Unifying USB Receiver (or Logi Bolt Receiver on newer models).

• Bluetooth Low Energy.

Easy-Switch: A dedicated button allows the user to easily switch control between two paired computers.

Logitech Flow: Compatible with Flow technology, which enables seamless cursor movement between up to two computers (even across Windows and macOS), allowing you to copy and paste text, images, and files between them.

Battery: Uses a rechargeable Li-Po ($500\text{ mAh}$) battery.

• A full charge lasts up to four months (or up to 70 days for the S model).

• A one-minute quick charge provides up to a full day of usage. Charging is typically done via a Micro-USB or USB-C port.
