The only problem with the Concord case is that it lacks something very important - suspension. So when the violin is in the case, its back is in contact with the case, ie. if you hit the case, you also pretty much directly hit the violin. Even though the shell is pretty strong and unlikely to break the violin will recieve the impact. In most cases apart from the very beginner foam ones, the violin is 'suspended' so it isnt actually touching the back of the case.
I wouldn't reccommend it for this reason, but if you are only taking it on easy journeys where it wont get knocked, it's probably adequate.
A case around the same price (?80) that is far better is the 'young korean' shaped ones which are on this website http://www.stringsexpress.co.uk/acatalog/c...aped_Cases.html
if you scroll down. There is also the gewa concerto which I and a ton of other people highly reccommend!
I think even this one would be better than the concord http://www.caswells-strings.co.uk/shop/vio...iolin-case.html
Despite the concord having a good strong shell i'd feel nervous putting any violin over beginner quality in it
Does it have to be shaped? You could get a bam oblong case for under ?100 and they are light
