Finally got mine.
Works pretty well and looks like something out of SS Enterprise.
The screen is great and the function to change the configuration is also
fantastic, so you can configure your buttons to work differently based on
whether you are in modelling, assembly or drawing mode and you need not
remember what you configured each button for.
The motion and mechanism is basically the same as the Sball. I personally
was very used to the ball and it will take me a while to get used to this,
knob, but I haven't taken a dislike to it.
