"We reinvented the wheel. All-new MagSpeed™ Electromagnetic scrolling is precise enough to stop on a pixel and quick enough to scroll 1,000 lines in a second. Oh, and it’s nearly silent.
The wheel’s machined steel gives it a premium tactility and enough weight to offer a dynamic inertia you feel – but don’t hear."
However, almost every time I scroll (ratchet mode) and let go of the wheel, I hear this spring noise like it has trouble snapping back to standstill. I've made a video where you can hear and see the problem.
I have chatted with support (who asked the internal team about it) and he said it's normal behavior! It's incomprehensible to me that a product that is marketed as "silent" is actually the loudest mouse I've ever had.
