Overclockers Club published a review on the Logitech G600 MMO Gaming Mouse
A quote from the article:
The mouse really is all that and a bag of chips. You've got your standard mouse functionality followed up with an added tilt wheel and twelve buttons to do nearly anything you can come up with. You have the option to use the G-Shift button to add in a full second set of 19 buttons as well as a mode selector to add in basically two more sets of twelve to the game. You can set three saved profiles to the mouse to take with you on the go and additional to your local machine for all the games and programs you desire. The Logitech G600 is quite the work of art in more than just the gaming world.Logitech G600 MMO Gaming Mouse Review @ OCC
