Logitech has officially expanded its value-focused Signature Series lineup in India with the debut of the Signature Comfort Plus M850 L and the Signature M840 L wireless mice. Moving away from the symmetrical form factors of older entry-level models, these right-handed, sculpted productivity mice are designed to minimize repetitive hand strain for professionals juggling long hours across multiple devices.
Key Highlights and Architecture
-
Built-in Palm Cushion: The Signature Comfort Plus M850 L marks Logitech’s first-ever consumer mouse to integrate a dedicated soft foam palm cushion right into the top shell. Combined with a molded thumb rest and extended rubber side grips, it promotes a natural resting posture for the hand.
-
Silent Clicks & SmartWheel: Both models utilize silent microswitches on the main buttons to significantly minimize workplace distractions. Navigating spreadsheets or long web articles is managed via Logitech’s adaptive SmartWheel, which seamlessly switches between line-by-line precision and high-speed scrolling.
-
Multi-Device Flow: Built on Bluetooth Low Energy, the integrated Easy-Switch button allows users to pair and instantaneously toggle control between up to three independent hosts—including Windows, macOS, ChromeOS, iPadOS, and Android.
-
Granular Customization: Using the proprietary Logi Options+ app, users can customize up to six programmable buttons, tweak precise DPI metrics (from 400 up to 4000 DPI), map app-specific navigation profiles, and configure automated workflow sequences via Smart Actions.
Enterprise-Ready and Green
For commercial environments, a dedicated Signature Comfort Plus M850 L for Business variant has been introduced. This edition drops standard Bluetooth-only pairing for a secure, anti-interference Logi Bolt USB-C wireless receiver designed for dense office environments. IT administrators can seamlessly monitor hardware fleets and manage mass firmware pushes using the Logitech Sync dashboard.
Logitech has also built the lineup around modern environmental standards:
-
Recycled Plastics: Post-consumer recycled (PCR) certified plastics make up between 49% and 77% of the total internal and external plastic components, depending heavily on whether you select the Graphite or Off-White color options.
-
Extended Longevity: Both units operate on a single, user-replaceable AA battery that provides a runtime of up to two years (24 months) before requiring a replacement.

The new models are landing across major retail channels and online marketplaces in India with the following official launch pricing:
