Product Overview

MagSpeed adaptive scroll-wheel

The speed-adaptive scroll wheel shifts between two scrolling modes automatically. As you scroll faster, it will automatically shift from line-by-line scrolling to free-spinning.
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. In the Logitech Options+ Software, you can decide to disable smart-shift if you prefer to stay in a single scrolling mode and always shift manually. You can also adjust the smartshift sensitivity, which will change the speed required to automatically shift into free spinning.
