I already send a technical support yet still havent received any reply since 4 days ago.
When i move around the mouse, cursor then slowly shifted/moved to the top left. Already tried changing lift off distance, use different surfaces, it's still the same prob. I'll PM if need more information.. fast reply pls it has been 6+ months since I purchased this mouse and i thought this were because of my mousepad. Also when i use the mouse at 45~ish degree on my cmstorm power-rx mousepad, the tracking just went horrible and got this staircase effect on the cursor movement.
