I have been using Razer Deathadder for less than three months, and so far it has not given me a pleasant experience. For some reason, the laser at the bottom of the Deathadder is so sensitive that (without putting the mouse on a flat surface) it can move the cursor while it is in the air. This result can be very annoying when I am playing fps games as I tend to lift my mouse up and down a lot. It is just a habit of mine when gaming. Can someone please explain to me on how to fix this?
