A very unique sensor. Cursor movement depends on the physical position of the mouse. It will not work to draw a straight line by slightly skewing the mouse (to the right or to the left), the line will shift towards the skew. It is very strange, because the hand with the mouse never lies strictly vertically, there is always a natural skew to the left for right-handers and to the right for left-handers. I will try to get used to the week, if it does not work out I will return.
