Logitech M500s Advanced Wired Mouse

You can scroll continuously, but also with the stepped setting you can scroll far through the weight of the scroll wheel with a single swipe.

First the good news: the scroll wheel goes really fast, and continues to rotate (for a long time) when you let go of the wheel. If you have a lot of web pages to search, this is your mouse. I even reduced the scroll wheel speed from 3 lines to 1 in the mouse settings, and it was still lightning fast. This also mentions the disadvantage: the wheel continues to rotate for many seconds, even if you then move your mouse over other applications. Suddenly you see your Excel, Word, Powerpoint ... pages scrolling in the background. You are scrolling through your Excel or PowerPoint, want to copy something with Ctrl-C, and suddenly you are zoomed in by a factor of 1000, because the wheel is still spinning for seconds, and scrolling with the Ctrl key pressed is the zoom function in Office . It really is a learning curve to put the wheel back when you don't need it. Then comes the next problem: the wheel has no hysteresis. If you keep your finger on the wheel, you are constantly going up and down. Even when moving your mouse, the scroll wheel sometimes gives a few hits. Are you giving a presentation with the mouse, and suddenly you are 1, 2 or 3 slides further because the wheel has moved. The worst thing is that with me the wheel had a minor imbalance. When I scroll through pages and I stop, the wheel tends to roll back a bit. And that made it completely useless. In short: great fast mouse for browsing, difficult learning curve in normal use, and even counter-productive for office or graphics work and gaming.

installing the extra mouse buttons is a huge challenge on a mac.
