This is what I love about the MX Master 3, it's like a hybrid for this where it has precision scrolling when moving it slowly but give it a flick and it will automatically unlock and go into smooth scrolling. https://youtu.be/KTzZui0nrrs

Logitech owns a patent[0] on this mechanism which prevents it from being incorporated in other products (without licensing it).

> The present invention generally relates to a control device, such as a mouse, and more particularly relates to multi-mode roller for a control device having a selectable smooth-roller mode and a ratchet-roller mode.

I find this feature annoying and am very unhappy when it randomly activates due to some driver bug (requiring me to open the Logitech software and possibly reboot the mouse).

Yeah I’m addicted to it. I can't use any other mouse since trying the Mx Master 3 scroll wheel.

I switched to an Elecom huge trackball and miss that wheel every single day.

A year ago I figured out I could use a spare button to toggle using the trackball itself for free scroll, total game changer, but still miss that wheel.

MX Anywhere 3 also has this, the only ambidextrous option!

No. It's fake ambidextrous like most of Logitech's mice. It has buttons only usable by the right thumb and a subtle change in shape to accommodate them. The G903 is actually ambidextrous letting you customize whether you want buttons on the left or right side and still has the same sort of scroll wheel (although not automatic but I hate that feature anyways).

I click forward/back with my ring finger, but I guess it depends on your grip how achievable that is.
