I've had my Razer Diamondback for about a year and a half now, but something that has slowly been pissing me off. I will be scrolling down and the computer thinks I'm scrolling up. Eventually it will go the right way, but not after playing tug of war with the scrolling. I have instead been using the scroll click to browse the interwebs. This is something I noticed early on, but was just to lazy to contact customer support and it isn't that hard to deal with. I am just getting frustrated with this.
