The M55 WIRELESS pairs responsive tracking up to 24,000 DPI with a slim symmetrical shell, offering a practical mix of precision and comfort for a wide range of hands and grip styles.

Key Features

• Compact Symmetrical Shape: The streamlined, ambidextrous design fits many hand sizes and grip types, making quick flicks and sustained aim comfortable in prolonged play.

Who It's For

The M55 Wireless is best for FPS gamers and general PC players who want a lightweight, ambidextrous mouse with dependable wireless performance and exceptional battery life.
