Logitech MX Master 4 Review: A Quietly Brilliant Upgrade

The Logitech MX Master series has long been a favorite among professionals who value precision, comfort, and seamless workflow integration. With the MX Master 4, Logitech refines an already excellent design, making subtle but meaningful improvements that enhance the overall experience.

If you’re looking for a mouse that effortlessly blends productivity and comfort, the MX Master 4 might just be the perfect fit—assuming you don’t mind its premium price tag.

Design & Comfort: Subtle Refinements

At first glance, the MX Master 4 looks nearly identical to its predecessor, the MX Master 3. The ergonomic shape remains, cradling your hand in a natural position that reduces strain during long work sessions. The textured grips on the sides provide a secure hold, and the thumb rest is as comfortable as ever.

Logitech hasn’t overhauled the design, and that’s a good thing—why fix what isn’t broken? Instead, they’ve refined the materials, making the mouse feel even more premium. The scroll wheel retains its satisfying magnetic click mechanism, allowing for both precise, ratcheted scrolling and ultra-fast free-spinning mode.

Performance & Features: Precision Meets Intelligence

The MX Master 4 continues to use Logitech’s Darkfield sensor, which tracks flawlessly on almost any surface—even glass. The sensitivity (up to 8,000 DPI) ensures smooth, accurate cursor movement, whether you’re editing detailed spreadsheets or fine-tuning graphic designs.

One of the standout features is the thumb wheel, which is now slightly more tactile. It’s perfect for horizontal scrolling or adjusting settings in creative apps like Photoshop or Premiere Pro. The side buttons are well-placed and customizable, letting you assign shortcuts for efficiency.

Logitech’s Flow technology is still a game-changer if you work across multiple computers. Seamlessly move your cursor between devices (even across different operating systems) and transfer files with a simple drag-and-drop—no extra software needed beyond Logitech Options.

Battery Life & Connectivity: Reliable as Always

The MX Master 4 charges via USB-C, and a full charge lasts weeks, even with heavy use. If you’re in a rush, a quick 3-minute charge provides hours of usage. It connects via Bluetooth or Logitech’s Unifying receiver, ensuring a stable connection without lag.

Should You Upgrade?

If you already own an MX Master 3, the improvements here might not justify an upgrade. But if you’re coming from an older model (or are new to the series), the MX Master 4 is a polished, near-perfect productivity mouse.

Pros:

• Excellent ergonomic design
• Smooth, precise tracking
• Great battery life with USB-C charging
• Useful thumb wheel and customizable buttons
• Logitech Flow for multi-device control

Cons:

• Expensive
• Not drastically different from the MX Master 3

Final Thoughts

The Logitech MX Master 4 doesn’t reinvent the wheel—it simply makes a great mouse even better. If you spend hours at your desk and value comfort, precision, and smart features, it’s a worthy investment. While it may not be a must-have upgrade for existing MX Master 3 users, for everyone else, it’s one of the best productivity mice available.
