New Engineering Mouse - X2 Creative @ Space

It's more like a flight game handle. It changes the tradition by holding the mouse in a vertical way to reduce fatigue. The left and right buttons of the mouse are located on the front, while the scroll wheel is on the top, which is manipulated by the thumb. Although this mouse can reduce fatigue, I feel that it should not be easy to control, it will take some time to get used to it. It costs 74 US dollars.
