Does what it says on the tin!
It’s a great vertical ergonomic mouse for righties. I was crippling myself using a claw like hand posture on an Apple Magic Mouse for work, it was bad. So I switched to this one and it’s like night and day. So much better on not just my hand and wrist but also my shoulder. It’s a thorough improvement. Also if you use multiple computers as I do, there’s a handy dandy button on the bottom that alternates to three different Bluetooth connections, so that’s convenient as well. The customizable buttons and Logitech software allowed me to replicate the main functionality I was missing from the Magic Mouse, which was horizontal scrolling. With those on the thumb buttons, I’m as fast and precise as before, only more comfortable and not doing medical harm to my body. Oh, last thing and my only tiny nitpick, is the scroll wheel. The way it’s designed, the skin of your index finger can get caught between the wheel and the mouse buttons, it’s annoying but that’s really all I can say about it. If they tightened the clearance on that component, I’d have nothing at all to say. And a few days into using it, I don’t even mind that so much. But if you’re listening Logitech, fix that in the next revision!
