content: I bought BOTH the Krait and the Deathadder and have used both for several weeks. I like the Krait better because it is lighter, smaller, easier to use with your fingertips (instead of resting your whole hand as on the Deathadder), and the mouse buttons are quicker and easier to click. Krait is a bit of a narrow mouse but is easy to adapt to. Some may like the "full-bodied" feel of the Deathadder which I can appreciate, as well. Love the super-high responsiveness of both mice and fast tracking that never faults. You cannot go wrong with either of these top-end mice.
