I was looking for a keyboard bag for my Roland VR-09 and then I found out about this flight case.
While it might not be the toughest case I've seen in my life, I think it could suffice occasional flights. I doubt that instrument will be damaged, it's more plausible that the case my crack after, 100+ flights or something like that.
But, for everything else, it's incredible value for money. Wheels seems very stabile, handles are decent, and the foam securing JUNO-DS and VR-09 allows you to securely store adapter or cables behind the keyboard. Or maybe some dynamic mics as well!
