Pros: After adjusting the height and weight with the included instructions the mouse was a very comfortable fit for being ambidextrous and all of the buttons worked properly as did the wheel.

Cons: This is all mostly personal preference, but my biggest and only real complaint that I have is with how hard I need to press the left and right mouse buttons and much resistance is on the wheel. I know that it may all just need to be broken in before it works as smoothly and easily and my previous mouse.
