The Deathadder’s software is exactly the same software that you use with all other Deathadder’s. I was kind of hoping to see a different skin used to match the Transformers theme. You still have all of the typical Razer functionality including the ability to reprogram all five of the buttons (number five is the scroll wheel). On top of that you can also reprogram the up and down scroll function of the scroll wheel if you need more adjustability. You can turn both the scroll wheel lighting and the Transformer logo backlighting on and off separately.
On top of the standard list of things that you can reprogram each button to do; you also have the ability to program any single key or a full macro.
One of my favorite features is the ability to set one of the buttons to adjust your sensitivity on the fly. The Deathadder is limited to only a few adjustments on the DPI itself but this isn’t a problem due to the on the fly sensitivity adjustment. You also have the option to adjust acceleration, double click speed, windows pointer speed, and X and Y sensitivity.
