I bought the same setup. I found the mouse to be awesome because I could bind all of my spells and abilities for WoW on it (scroll up/down and left and right click on both wheels, plus the other buttons). But you're right, the bluetooth is weak once you get any distance away from the computer. Up close it works just fine. I have a razer mouse and it's much faster.
