Key Features & Benefits

• Stay Comfortable Through Longer Workdays – Integrated Palm Cushion
  The M850 L introduces Logitech's soft palm cushion, supporting the hand as you work and helping reduce the small pressure points that can become noticeable during extended desk sessions.
• A More Natural Fit for Your Hand – Sculpted Right-Handed Design
  Its contoured shape is designed around right-handed users, while comfortable side grips help provide a secure, relaxed hold when you're moving between documents, browsers and applications throughout the day.
• Move Precisely at Your Preferred Speed – 400–4000 DPI Tracking
  Advanced Optical Tracking offers sensitivity from 400 to 4000 DPI, adjustable in 50 DPI increments through supported Logitech software. Choose slower precision for detailed work or increase sensitivity to move quickly across larger displays.
• Fly Through Long Documents – SmartWheel Scrolling
  SmartWheel gives you precise line-by-line scrolling when reviewing detailed content, then lets you move rapidly through long webpages, spreadsheets and documents when speed matters.
• Create a Quieter Workspace – Silent Touch Technology
  Logitech's Silent Touch technology reduces clicking noise by up to 90%, making the M850 L especially suitable for shared offices, home working, libraries and late-night productivity.
• Move Between Three Devices Effortlessly – Easy-Switch
  Pair the mouse with up to three compatible devices and switch between them using Easy-Switch, ideal if your workflow moves between a desktop, laptop and tablet during the day.
• Shape the Mouse Around Your Workflow – Customisable Buttons
  Four buttons can be customised through Logi Options+, allowing frequently used shortcuts and actions to sit directly under your fingertips instead of being buried in menus.
• Get Faster Access to Everyday Tools – Actions Ring Support
  With supported Logi Options+ features, the Actions Ring can place commonly used tools and shortcuts within quick reach, helping reduce repetitive navigation during everyday tasks.
• Connect Without Filling Your Desk with Cables – Bluetooth Wireless
  Bluetooth Low Energy connectivity provides straightforward wireless pairing with compatible computers and tablets, helping keep your workspace cleaner and more flexible.
• Work Across Multiple Operating Systems – Broad Compatibility
  The M850 L supports compatible Windows, macOS, ChromeOS, Linux, iPadOS and Android devices, making it a versatile choice for mixed-device households and professional environments.
• Spend Less Time Replacing Batteries – Up to 24 Months Battery Life
  Powered by a single included AA battery, the mouse offers up to 24 months of battery life under Logitech's test conditions, reducing interruptions and ongoing maintenance.
• Move Around Your Workspace Freely – Up to 10m Wireless Range
  A wireless range of up to approximately 10 metres under suitable conditions gives you more freedom when using laptops, presentation setups or flexible workstations.
• Keep Important Controls Within Reach – Six-Button Layout
  Six controls include left and right click, middle SmartWheel click, back, forward and DPI control, providing more productivity options than a basic three-button mouse.
• Better Suited to Medium and Larger Hands – M850 L Size
  The approximately 121.3 × 74.3 × 44.2mm dimensions provide a fuller grip than compact travel mice, helping the hand rest more naturally during extended use.
• Comfort Without Unnecessary Weight – Approx. 103g
  At approximately 102.9g including the battery, the M850 L provides a substantial, controlled feel without becoming excessively heavy for everyday desk use.
