Right-handed comfort mouse

The Logitech Signature Comfort Plus M850 L is a right-handed wireless mouse shaped with a built-in palm cushion. It targets office workers and home users who want quiet operation and all-day comfort. The optical sensor reaches 4000 dpi for precise cursor control on most surfaces.

Check Bluetooth and button layout

Verify that your computer supports Bluetooth pairing before ordering, because the mouse has no USB receiver. Confirm that six programmable buttons suit your workflow, as the layout is fixed. The product works with Windows and macOS, so ensure your OS version accepts standard HID devices.

Palm cushion and silent clicks change daily feel

The integrated palm cushion raises the heel of the hand to reduce wrist strain during long sessions. Silent click switches lower audible noise in shared spaces. Together they shift the experience from a standard flat mouse to one designed for quieter, more relaxed use.

Questions about this item

What comes in the box with the Logitech Signature Comfort Plus M850 L mouse and do I need to buy batteries separately?

The package includes the mouse itself and a USB receiver for wireless use. Two AA batteries are pre-installed so the mouse works immediately without any separate purchase.

How do I decide which DPI setting to use on the 4000 dpi sensor?

The sensor reaches 4000 dpi maximum sensitivity. Lower settings suit precise tasks like photo editing, while higher settings let you cross large or multiple monitors with less hand movement.

What does the 4000 dpi figure mean when I am actually using the mouse?

At 4000 dpi the cursor moves 4000 pixels for every inch of physical travel, giving very fine control on high-resolution screens or fast navigation across wide desktops.
