Mday: Do you have alot of RF devices around your computer? Like wireless remote control, WIFI ect? Or are you using your mouse on a metal table? Or is it the wireless phone? I am using this baby on my wooden tablen and it works nicely, range is like a meter nothing more and nothing less. And I dont have tracking problems, the left and right buttons are pretty stiff though and that brings to me that this mouse is not for kids younger then 7 I guess. You got to press hard in order for the button to depress. And when it does I will immediately see a blue blimp on the reciever.
In anycase, I have to tell you that this mouse is not made to be used across the room. Rather as a convenient replacement for the touch pad while you are traveling. Its also not for gaming either. I tried it on WC3, UT2003 and got frag easily.
And if you are having problems with the mouse moving or receiving clicks, press the tiny button on the receiver and wait for the blue light to stop blinking and by then you should get your secure connection between you receiver and your mouse. BTW, I am using it with a laptop too and I didnt have to even install any software, matter of fact the usual Window has detected a new device message DID NOT even show up. I just plug it in and press the button on the receiver and then let it work.
Further more after a long period of no use, the mouse will turn itself off. And in order for you to reactivate it, you will have to press the button on the receiver and hold it for like a second or 2 before you will get the blinking blue led. Make sure that when you press the button on the receiver, your mouse is inactive, that is your mice's red led is off, if its on press the button at the bottom of the mouse to inactivate it and then press the button on the receiver. Then the blue led on the receiver will start to blink otherwise it will not.
Hope that helps. Good luck to those with problems. And thanks for the hot deal again, been waiting for a wireless optical mouse and I finally got it for 19.99 YESSSSSSSs
