Logitech MX Master 4 Unboxing: First Look at Haptic Feedback, Auto-Scroll, and Colors

Unboxing the MX Master 4

• 📦 The unboxing reveals the Logitech MX Master 4 mouse in both white and black color options.
• 🔌 A significant improvement noted is the inclusion of a USB-C charging cable instead of the older, bulkier USB-A dongle.
• 📄 Standard documentation is also included in the box.

Key Features and Innovations

• 💡 The mouse features a haptic feedback button, which initially seemed like a gimmick but works well, though it deactivates when the mouse is in sleep mode.
• 🖱️ A standout feature is the automatic infinite scroll wheel, which transitions from stepped scrolling to free-spinning based on the flick of a finger, a change from previous models that required manual switching.
• 🤫 The mouse boasts super quiet switches for clicks, with the sound barely audible even when placed next to a microphone.
• 🌐 The sensor is designed to work on virtually any surface, including glass.

Design and Ergonomics

• ⚫ The black model features semi-translucent buttons on the corners, a subtle aesthetic touch.
• 💨 A change from previous models is the plastic textured back instead of rubber, which is expected to be easier to clean and less prone to accumulating grime.
• 🖐️ The mouse maintains an ergonomic design for comfortable workflow, with thumb buttons and a scroll wheel.

Connectivity and Power

• 📶 The MX Master 4 supports Bluetooth connectivity for up to three devices and includes a dongle for a stable, improved connection.
• ⚡ It features an 8,000 DPI sensor, with a higher 12,000 DPI mentioned for comparison, though the difference is less critical for workflow.
• 🔌 Instead of a battery compartment for AA batteries, the mouse has a front-facing USB-C charging port.

Battery Life Speculation

• 🔋 While specific battery life is unknown, the implementation of haptic feedback and the auto-scroll mechanism might slightly reduce battery longevity compared to older generations.
• ⏳ However, based on the performance of older Logitech mice, it's speculated that the battery will still last for a considerable time, potentially a year or more.
