This is a very well-made flight case and workstation.
It fits the device perfectly. The only downside is that the controller is so large, and because the case is of such good quality, it is quite heavy.
However, a plus is that there are decent wheels on one side of the case, so it doesn't have to be lifted from A to B.
Except for the weight, I'm not sure you could do much to improve it, I would recommend this if you have a RANE FOUR to want to move around.
