I'm using it hevily since almost 2 years , it is surely built to stand time and bad treatmens.
I use it to store a 3-cords-cable (7 mtrs), the keyboard stand, an FCB1010 and some spare cables, it totally nails the work, and it also have two big pockets on the front where to store strings packs, some coloured tape and various tools like wrench and screwdrivers.
The zippers are military-grade alike, big and solid, both on the main closure and the pockets.
The handlers are regolable and sturdy.
Only "issue", it is BIG (as you can see from the measures), so not easy to handle around and is not really padded, so if you plan to have inside a keyboard with pots you should consider storing/handling it carefully.
