Isn't the Trasformer edition quite common in shops in the Klang Valley? Sunway Pyramid got alot of outlets selling.

No lo, the Yellow Bumblebee ones are common. But the Decepticons are harder to find.

Prediction ain't good for FPS games brah.

Imagine if you are trying to headline then suddenly the auto correct kicks in and aim the wall instead. Confirm rage.

Hang as in the cursor jitter or shake? Or respond slower than usual? If it's jitter/shake, could be the sensor. If slower, check the settings. Try reset-ing it to default and reconfigure.

Try updating the firmware. If the problem still persist, you should try to RMA your mouse if it is still on warranty. I had a mouse with Jitter issues too, it was caused by the sensor.
