PRODUCT DESCRIPTION
Logitech Signature Comfort Plus M850 L Off White Wireless Mouse (910-007734) - 2 Years Local Warranty
Cushioned Ergonomic Mouse for All-Day Comfort
The Logitech Signature Comfort Plus M850 L Off White (910-007734) leads Logitech's Comfort Plus series with a built-in palm cushion that supports your hand through the whole working day. The full-size, right-handed shape keeps wrist and palm relaxed, ideal for professionals at the desk for long hours in offices, hybrid and home workspaces.
Built-In Palm Cushion and Silent Clicks
The integrated palm cushion delivers soft support exactly where the hand rests, hour after hour. SilentTouch switches reduce click noise while preserving tactile feel, keeping meetings and open-plan offices calm. Six buttons — including back, forward and a DPI button — keep navigation and speed control at your fingertips.
Multi-Device Switching and Customisation
Pair up to three devices and switch between laptop, desktop and tablet in an instant over Bluetooth Low Energy — no dongle required. Buttons are customisable through Logi Options+ on Windows and macOS, and the SmartWheel scrolls line-by-line or flicks through long documents.
Adjustable Precision and 24 Months of Battery
The optical sensor tracks from 400 to 4000 DPI (1000 nominal), with a dedicated button to shift sensitivity on the fly. A single AA battery keeps the mouse powered for up to 24 months, making it a low-maintenance, comfort-first standard for any desk.

Frequently Asked Questions — Signature Comfort Plus M850 L
What is the difference between the Graphite and Off White M850 L?
Only the colour differs. Both Graphite and Off White share the same built-in palm cushion, 6 buttons, 400–4000 DPI sensor and Bluetooth connectivity.
Does this mouse include a USB receiver?
No. The consumer Signature Comfort Plus M850 L connects over Bluetooth Low Energy only — no dongle is required. If you need a Logi Bolt USB-C receiver for a managed deployment, the MK880 combo bundles the M850 with a USB-C receiver.
How is the M850 L different from the M650?
The M850 L is larger with a built-in palm cushion for full palm support and adds a DPI button and Easy-Switch across three devices. The M650 (in the MK650 combo) is a mid-size mouse without a DPI button or device switching.
Can I switch it between my laptop and tablet?
Yes. Easy-Switch pairs up to three Bluetooth devices so you can move between a laptop, desktop and tablet instantly.
Does it need any software or licence?
No licence is required. Logi Options+ is a free, optional download for button customisation and on-the-fly DPI control.
How long does the battery last?
Up to 24 months on a single AA battery, which is included and user-replaceable.
Does the M850 L come with a Singapore warranty?
Yes. Every Signature Comfort Plus M850 L sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
