Logitech Ergo M575 vs Logitech MX ERGO

The learning curve for using this sort of mouse is pretty minimal, especially if you've played games on console and use a joystick to move the in game cursor. I have a couple of personal issues with this mouse. The ergonomics for me are not that optimal as: my hands are big and I prefer a more vertical tilt. The mouse would feel great for me if the tilt was slightly more aggressive and my hand (which is slightly above average) hangs off the side of the mouse

Clad in grey, with a silver bottom plate and a silver trackball that vaguely evokes the constellations in the night sky, the MX Ergo looks great on a desk. Sure, it's not very colorful, but you're likely to be using it next to a grey or black keyboard, as well as a dark-colored laptop or display, so it probably won't clash as much as, say, the fiery red ball on the Trackman. That the MX Ergo looks so good is fortunate, because at its $100 list price, it's bordering on status symbol territory, especially since you can find several very good mice for half that price.
