Pros: Loads of buttons, easy to adjust weight and shape. I love the press and hold 'lower dpi' button. I feel like I save a good deal of time using mouse shortcuts over keyboard shortcuts for editing images. The software makes it pretty easy to bind keystrokes to the various mouse buttons.

Cons: It took a month to be comfortable with the mouse.

Overall Review: This mouse had a pretty steep adjustment curve. I struggled with FPS type games for the first 3-4 weeks of owning this mouse, but now everything is great. If you happen to use this mouse for both gaming and for work (any software that uses a ton of shortcut keys) then this is the best mouse for you. If you only need a gaming mouse, then you may want to find a cheaper Cyborg.
