If any of you are fortunate enough to visit CERN in Geneva, there's a mouse museum:

I'd be particularly interested to see a decap of a PixArt chip (e.g. PAW3515DB). The USB circuitry is included in the same package as the CCD sensor, and I'd like to see how they do that! I also imagine that the die geometry is quite large, because power requirements aren't a major concern, but cost is. It would also be nice to see Ken Shirriff do a historical write up of mice over the generations.

It says it's "designed for 3D CAD use". I know nothing about that but maybe if you search in that space you'll find more choice.

For example to quickly scroll down a long page, just disconnect the brakes and roll the wheel, it will just keep going. Or testing infinite scroll feature, just let the wheel go.
I had one mouse like this that I loved but it broke eventually. Now the only one I've been able to find is a gamer mouse with a bunch of unnecessary feature.
I've heard used with sufficient persuasion or with sufficient encouragement, but yours is a new one. Remind me to not tap on your shoulder while deep in the zone.
Logitech calls it SmartShift and other people have reported the same issue, SmartShift enables itself, and from that point onward no settings changes will disable it.
It's pretty frustrating to say the least, the MX Master 3 was poised to fix the reliability issues the previous entries had otherwise (since replaced the physical scroll wheel click with an electromagnet in a very convincing way)
I assume that firmware updates have done nothing to help you?
Found it on a Danish site, it's not impossible to order but it's not obviously available here. Thanks stranger!
