Great option. Expensive, but if you spend a lot of time at the computer and worry about tunnel syndrome, it's a must. As for me, it's even moons and more convenient than a vertical mouse. Got pros: Excellent ergonomics. In one working day, I got used to the mouse, now I donโt want to change it for something else. Convenient application for Mac and Windows. Fast and convenient switching. Some cons: I did not immediately get used to the wheel with two scrolling modes. But now everything is fine.
