Wireless mouse Immer SM-S4000

The Immer SM-S4000 is a sleek, ambidextrous wireless mouse designed for everyday use. Its compact yet ergonomic shape fits comfortably in either hand, making it suitable for both right- and left-handed users. The matte finish on the top surface provides a smooth feel and ensures precise cursor movement without slipping during extended sessions.

Equipped with a 1600 DPI optical sensor, the SM-S4000 offers reliable tracking on most desk surfaces, from wood and plastic to dedicated mouse pads. This DPI level strikes a balance between accuracy and speed—perfect for web browsing, office applications, and light gaming. Navigation feels responsive, whether you’re editing documents or scrolling through large spreadsheets.

Connectivity is handled via a 2.4 GHz USB nano receiver. Simply plug the small dongle into any available USB port, and the mouse immediately connects in a plug-and-play fashion—no driver installation required. The effective wireless range extends up to 10 meters, giving you freedom to control presentations or home media centers from across the room.

The SM-S4000 runs on a single AA battery (not included). With its power-saving features—such as automatic sleep mode after periods of inactivity—you can expect up to 8–12 months of typical use on one battery. A small LED indicator subtly notifies you when battery levels are low, so you have enough time to replace it without sudden downtime.

Four tactile buttons (left click, right click, clickable scroll wheel, and back/forward side buttons) enhance productivity. The side buttons can be used for quick “back” and “forward” navigation in web browsers or mapped to custom shortcuts in various applications. All switches provide a crisp, consistent click feel that holds up well over time.

In terms of compatibility, the Immer SM-S4000 works out of the box with Windows XP and newer (including Windows 7, 8, 10, and 11), Linux distributions, and basic cursor functionality on macOS. Note that some secondary button functions (like side-buttons) may require third-party software or may not function on certain macOS versions.

Overall, the Immer SM-S4000 is an affordable yet dependable wireless mouse. Its straightforward setup, long battery life, and ambidextrous design make it an excellent choice for students, office workers, and casual home users who need a reliable pointing device without breaking the bank.
