I guess it depends on what you mean by "enough". If you aren't flying and checking your guitar, I'd say it is probably enough to protect the guitar in most situations.

G&G is the same company that makes the cases for Fender's AVRI line and custom shop stuff. I have another G&G case for my Jazzmaster, and the two are essentially the same. For hauling the guitar to gigs and practice in my car, the case is fine. If I were flying with it, I'd probably want an ATA style case. But the G&G case is still a very nice case.
