Long winding wires often end up in tangles and add a risk factor in the heat of gameplay.  Razer addressed this problem with the Razer Armadillo, the world’s first intelligent cable management system. Striving for perfection, our engineers at Razer reengineered the product to further improve the original design. The Razer Armadillo² is now lighter in weight with a unique intelligent design which allows you to insert and remove the cable within seconds. Now you can enjoy the freedom of wireless play on your wired mouse.
