I am looking for a new mouse. I currently am using a sensei which is ok. The sensor is all goofed and shape is ok. Primarily looking for fingertip mouse. Something light with a good sensor. I was looking at the G303 and it looks perfect but I have read many reviews of the sensor shaking and causing jitter from it shaking. I was just wondering if they have put out new batches and fixed this and would it be safe to buy one now or wait.
