The verdict

Our bottom line after lining up both full reviews.

Bottom line

For most everyday office and productivity users, the Logitech MX Master 3S stands out as the superior choice. Its exceptional ergonomic comfort, silent clicks, and highly versatile scroll wheel provide a premium and efficient user experience. With a reliability score of 88.0, owners report consistent performance and durability over time. While the Keychron M3 offers compelling value and strong multi-device connectivity, its lower reliability score of 73.0 and recurring reports of dongle issues and inconsistent high-polling-rate performance prevent it from surpassing the MX Master 3S. If comfort and consistent, refined performance are your top priorities, the Logitech MX Master 3S is the better investment.

Performance

The Logitech MX Master 3S excels in daily productivity tasks, offering smooth, precise tracking and a highly praised scroll wheel. The Keychron M3, while offering good general performance, is particularly strong for users who need to switch between multiple devices. However, some Keychron M3 users report occasional performance issues when pushing its higher polling rates.

Durability

Owners report the Logitech MX Master 3S is a very durable mouse with a high reliability score of 88.0, often lasting for years of heavy use. The Keychron M3 has a lower reliability score of 73.0, with some owner concerns focused on the long-term reliability of its dongle and connectivity features. It doesn't quite match the MX Master 3S's track record for sustained robustness.

Community sentiment

The Logitech MX Master 3S enjoys widespread praise for its ergonomic comfort, quiet clicks, and versatile scrolling, making it a favorite for many professionals. Keychron M3 owners appreciate its good value and flexibility for multi-device setups. However, the Keychron also sees more complaints about specific technical glitches and inconsistent performance, especially compared to the premium Logitech offering.

What you give up when you pick one over the other.

If you choose Logitech MX Master 3S
