This mouse is equipped with a very nice Roccat logo at the back of it which gives the mouse a nice extra touch compared to other mice on the market.
Roccat have placed two buttons on the left side that normally works as forward and back in a browser, the back button also works as a Easy-Shift button which means that when you push it down and push another button you can do an extra command. This means that all the buttons can work with two different pre programmed commands. For example in World of Warcraft the back button + the left mouse button could mean that you mount up onto your mount.
On the right side they have no placed any buttons most likely since it is not needed since there are double commands for all buttons, the right side is well shaped for your fingers though.
On the top you have three buttons and a scroll wheel which is one of the quietest scrolls wheels I have ever tested! The buttons on top usually are to change DPI on the fly.
