No. I literally mean like, you know how you can scroll swipe on mobile (or trackpad) and the page just keeps running. I think the scrollwheel should too, even if it wouldn't under it's own momentum, it should remain spinning in sync with the page (servo, I guess...?).

But I hadn't thought of your thing (the scrollwheel kind of stops and, I guess you mean, can't me moved further, once you reach the end of the page), and I like that idea! :)

If you go to major electronic shops: Better Buy, Stables etc... you can test mice like that.

Logitech, Microsoft. They have little flywheels that keep on going

The Logitech MX Master series has a heavy, (optionally) free-spinning scroll wheel.

It's the best scroll wheel I've ever used: night and day better than anything else. Scrolling through a long doc is a flick or two, and it just keeps rolling along, until you touch it and it stops instantly. It allows amazing precision.

If only the side-to-side scroller was as good ...

Unfortunately, it's prone to breaking.

There is a mechanism controlling the wheel mode that can mechanically get into a position where the magnetic control doesn't do anything.

Sometimes, thumping the mouse hard against your thigh helps resetting the mechanism, but sometimes not. My first one went out within warranty, I've got it replaced, but I'm sure this one will fail in a few months, as well.

Logitech probably saved a cent or two there, crippling an otherwise fantastic mouse.

My original MX revolution is around 15 years old and the scroll wheel still works fine. I did have to solder in some new microswitches for the main buttons, but that's not unexpected for the amount of use its had.

I think the mechanism was new for the MX Master.

Yeah mine has a motor that turns a detent ball, newer ones use a magnet I think
