I switched from the Razer Basilisk V3 Pro to this mouse looking for an ergonomic improvement to reduce wrist fatigue and this mouse does not disappoint, the addition of the side scroll button and the haptic button have been a game changer for me in terms of productivity and saving time during work hours. The battery is a huge jump compared to the Basilisk's battery (taking into account that this mouse does not have RGB like the Basilisk) if what you are looking for is to optimize your productivity and more importantly take care of the health of your wrist, this is the way to go.

Writing this review after using it for a month now: Connectivity is noticeably more stable via the Logi Bolt receiver compared to Bluetooth, with consistent performance and no observable input lag during extended usage. Customization through Logi Options+ unlocks the true potential of the MX 4, offering extensive button mapping and application specific controls that significantly improve workflow efficiency. What really stands out is the high-accuracy optical sensor with adjustable DPI (up to 8,000 DPI). It provides precise and controlled cursor movement, making it well suited for long hours of technical work such as software development. The ergonomic design helps reduce fatigue during extended coding sessions after using for more than 2 weeks. The MagSpeed scroll wheel adds substantial value, especially when navigating large datasets, long code files, or massive drum arrangements during music production. The seamless transition between precision scrolling and free spin mode makes timeline navigation fast and effortless. After using it for more than 4 weeks, the only downside is the weight of the MX 4, which may feel slightly heavy for users who prefer lighter mice or make frequent, rapid movements. However, this trade-off also contributes to its premium build and stability.
