Logitech MX Master 4 Mouse

The Logitech MX Master 4 is a premium wireless productivity mouse designed for people who spend long hours working at a computer and want more control than a conventional mouse can provide. Its large ergonomic shape, thumb-operated controls, MagSpeed scroll wheel, horizontal scrolling, 8,000 DPI Darkfield sensor, and support for up to three devices make it particularly well suited to office work, programming, spreadsheets, creative applications, and multi-computer setups.

The MX Master 4 also introduces haptic feedback and an Actions Ring, adding another layer of customizable controls through Logitech’s Logi Options+ software. These features can turn frequently used commands, shortcuts, and application tools into mouse-accessible actions, although their usefulness depends heavily on how much customization you are willing to do.

At 150g, this is not a lightweight mouse, and its large right-handed shape will not suit everyone. It is also considerably more expensive than basic productivity mice. The question is therefore not whether the MX Master 4 has more features, but whether those features actually improve your workflow.

For programmers, office workers, designers, editors, and anyone who frequently works across multiple applications or computers, the MX Master 4 offers a particularly feature-rich approach to desktop control. For simpler tasks, however, much of what you are paying for may go unused.
