Compared to the Razer Copperhead, Krait, and Diamondback, the DeathAdder is much larger when it comes to the physical size. In fact, when examining the Razer DeathAdder its size was reminisce of Microsoft's IntelliMouse. Another distinguishing factor of this mouse is that the top of the mouse has a rubberized feel to it. On the top of the mouse are the two buttons with scroll wheel as well as a glowing Razer logo. On the left hand side of the mouse are two additional buttons.
On the bottom of the mouse is a button (similar to the one found on the Copperhead) for profile switching. Also on the bottom are three large Teflon feet.
