Hi..any Deathadder 2013 user here and got problem like mine?
I noticed the scroll wheel occasionally squeaks while scrolling.
And when I push the scroll wheel from the rightside to the left, I get a very squeaky sound and the scrollwheel moves quite much. Now when I push the scrollwheel from the leftside to the right there is no movement and no noise at all.
I feel this quiet annoying. 
Damn, i'm just bought this mouse two days ago.. 
Can i request from shop to change to new one?..i dont want to rma because its will take long time 

Ya..im just plan go to shop tomorrow & demand to exchange new unit 
I dont want to take risk..scared later spoiled the electronic component
Oic..your scroll wheel silent and no weird sound?
