MagSpeed adaptive scroll-wheel

• Line-by-line (ratchet) mode — ideal for precise navigation of items and lists.

• Hyper-fast (free-spin) mode — near-frictionless spinning, letting you fly through long documents and web pages.

Switch modes manually

You can also manually switch between modes by pressing the mode shift button.

By default, mode shift is assigned to the button on top of the mouse. 

With Logi Tune, you have the power to set your default scroll mode — choose from SmartShift, Ratchet, or Free-Spin. You can also fine-tune the sensitivity, scrolling force, and scroll direction to match your exact preferences.
