It works very well at first but after two months it just sucks, you have to calibrate every 2 minutes and then there's another problem: If you have calibrated on the right hand and for some reason want to take it with the right hand, it will not work. I want to rotate the gimble when writing, good luck to you, because you will need it. You can't turn left or right, I can't speak English at all, you explain how much it sucks.
