This case is okay. Not much more to say than that. I wouldn't fly it...ever. The panels aren't particularly thick and are quite flimsy; you could bend and probably break them by hand, and there are no metal supports. It should hold me up for carrying it around to gigs or popping in the car for short tours, but I wouldn't trust it for much else above that.
The insides (under the lining) seem quite soft, and feel as if they'll collapse after a little while. There's also quite a lot of room around the guitar for it to move, so I'd be hesitant about knocking it around much.
If you want a proper hardcase for a guitar that's worth a lot, take at least one step up. For the casual player and gigger, this does the job.
