I have bought this flight case to fit my lights DMX mixer/controller.
The wooden supports on which the controller needs to be fitted are not compatible with my device, both for the holes where the screws go, and the inclination angle of the supports, which makes the controller too high to be able to close the cover on it. I will probably have to make some customisations, as there is not point in sending it back, either with some wooden supports, having the holes where I need them, and less inclination angle, in order to be able to close the lid of the flight case, or with some PLA 3D printed supports. I will experiment.
I would not rate is as a product flaw, maybe my DMX controller is just not following the standards.
Besides that, it seems well done.
So, once again take precise measures of your controller, and make sure that, once inside the flight case, the lid can be closed.
