Why do I have a razer mouse? I had to buy it at a big box store in a pinch and this was the only wired one they had.

To my surprise, this thing appears to actually have no planned obsolescence and it's still working after years and years of abuse.

So I think this model can join the old Microsoft Intelimouse on the list of mice that last forever.

I did have some issues with the scroll wheel and the middle mouse button, but they were fixed by just blowing air into the mouse and turning it upside down and slapping it to get some crud out.
