I have kept it unused. It's small but can hold a lot, and it's durable. It has many pockets and can hold a lot of items. The bottom pocket has darts, so it can accommodate thick items. The shoulder strap is detachable. The shoulder strap is adjustable, so you can use it at your preferred length. The back side has a cushioning material, such as a sponge, about 7mm thick. There is some clouding on the metal parts.
