I wanted to use the mouse pad with my RAT7 mouse from Cytec. Unfortunately, I realized that this is not possible, I is there from the very beginning had problems when up and down move the mouse, so when moving on the Y-axis my movement is sometimes not recognized at the 1st use. Then the cursor simply stops or moves jerky and uneven. When I move the mouse on the X-axis, however, it works flawlessly and also with my old Mousepad (SteelSeries QcK) I never had any problems ,.
So I can 4HD go because the error can neither work nor play.
