Query: very poor control with pointer

This is a huge disappointment. I have used the latest driver v5.5 and this mouse does not have anywhere near the type of smooth pointer control that you would expect, even compared to the original ball type mice. i have tried many types of mice over the years, including the optical usbs, wireless optical usb, logitech mx1000 laser, and of course the original ball driver types, and this one is by far the worst i have ever used. NOT RECOMMENDED!!
