Recently got a new mouse called the R.A.T. 9, by CyborgGaming.
The Cyborg RAT 9 is a gaming mouse, and it is awesome ‘coz you can do a lot of physical adjustments to the mouse. You can adjust the length of the palm rest, the distance of the thumb rest from the mouse, and other stuff like that. You can also add/remove weights as you like.
This is a gaming mouse, however you can also use it for your photography/editing or creative work. There are profiles available on their website, this includes gaming and non-gaming profiles.
