Query: Mouse did not work, bad software

This mouse is a great size and has a great look. However, when I installed the software for the mouse, I found that the mouse is completely unusable. The scroll bar was going out of control and the sensors on the mouse were all messed up. I purchased it brand new and had this problem. I contacted Microsoft and they were very helpful in getting a replacement. Don't purchase this item, too many problems with the intelipoint software.
