Signature M650

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.
