1-MagSpeed scroll wheel

You might be thinking, what makes magspeed scroll special? 

It’s special because not only does it offer precise, high-speed scrolling, but it also allows you to switch effortlessly between two scrolling modes automatically (step-by-step and free-spin modes).  

Thanks to electromagnetic technology, it provides smooth, silent scrolling with enough tactile control to stop on a single pixel when needed. The wheel is also made from machined steel for added durability and a premium feel, enhancing productivity for users working across documents or web pages efficiently.

A lower force will make the ratchet very subtle and smooth, while a higher force will make every ratchet very firm and precise.

2-Mode Shift Button 

This button is at the top of the mouse right behind the mag speed scroll wheel. 

Just like the precision and high-speed scrolling that makes the mag speed special, the mode shift button also offers flexibility, allowing you to manually shift between modes just by clicking on this button.
