Bought two of these cases for cables and accessories.
First impression was that I got what I had expected - not overly lightly built but not that sturdy either. The paddings (that need to be purchased separately) fit in nicely, and do a good job in protecting the contents.
On my first gig with these, the lid of one of the boxes was slightly nudged when open, and to my surprise the rivets on one of the lid hinges came off. Subsequently the lid was only held on the box by one hinge.
As it is clear that the lightly built hinges are not intended to take any load (not even the weight of the open lid), it would be good to have straps that limit the opening angle of the lid (to, say, 100 degrees at a maximum) so that the hinges or their attachments will not be strained.
