Signature M550

While all three mice share the exact same shape, silent-click buttons, and smart-scrolling wheel, they are tiered by features to match different workflows. The M550 is a button-free ambidextrous mouse; the M650 adds two customizable side thumb buttons; and the M750 expands on both by adding a top DPI button, multi-device switching for up to three computers, and cross-screen file sharing via Logitech Flow.

The SmartWheel is an adaptive scroll wheel that changes behavior based on how hard you flick it: If you scroll slowly, it tracks precisely, allowing you to move down a spreadsheet or document step-by-step. If you give the wheel a quick flick, it automatically releases into a fast spin mode so you can fly through pages or long websites instantly.

Logitech offers this mouse in two physical sizes to accommodate different hand sizes. Signature M550 is designed for small-to-medium hands. Signature M550 L (Large) is a scaled-up version intended for individuals with larger hands.

Yes. The M550 features Logitech's SilentTouch technology, which reduces more than 90% of the clicking noise compared to Logitech M185.

The M550 runs on a single AA battery (which comes included in the box). Thanks to its power-efficient design, the battery will last for up to 24 months (2 years) before needing a replacement.

Yes. Because the M550 lacks side thumb buttons, its physical shape is perfectly symmetrical and ambidextrous. Both left- and right-handed users can use it comfortably

Pairing this mouse is straightforward. Flip the mouse over, turn the power switch to ON, and press and hold the connect button on the bottom until the LED light starts blinking rapidly. Open your computer or tablet's Bluetooth settings, select this mouse (model name) from the list of available devices, and click connect.

No, it does not work well on clear glass. This mouse uses Logitech's Advanced Optical Tracking, which requires some surface texture to register movement. If you have a clear glass desk, you will need to use a mousepad.

To adjust the pointer speed, you must download the Logi Options+ software on Windows or macOS. The mouse features an optical sensor adjustable from 400 DPI up to 4000 DPI.

Yes, it has great cross-platform compatibility. It is "Works with Chromebook" certified and natively supports iPadOS (14 or later), Android (8.0 or later), and Linux. You can connect to these devices instantly via Bluetooth without installing any extra drivers.
