But sir, Kone XTD is wired, also, don't underestimate gaming mice! I spend a lot of money on my Roccat Kone Pure Optical but with Steelseries Qck they multiplied my k/d by 2 in FPS!Still never understood why anyone would pay so much extra money for a mouse just because it looks cool and is wireless. Ok first off if you have a desktop why would would you need a wireless mouse? That's stupid! And second any cheap $8 dollar optical mouse will do the same job and last much longer.
