I use a very unique mouse that I have been using for my whole time playing BF2.
So when my mouse started to wear out I went to buy a new one.
But soon found out Logitech have quit making them.
So Logitech came out with a new version the m570, and from most of the reviews that I read
It's too small to fit in the hand comfortably, it's made a cheap plastic, ect...
But I managed to find two of them on craigslist $30 bucks each still in the box.
Then I went on E-bay, there was two of them $166 each.
