It looks such as urethane form is made according to the shape of the saxophone to be stabled, but the one I bought doesn't appear so, it just has way too big and flat space, so the saxophone moves much in the case. It looks really different as they see on the picture.
It is convenient carrying but also are afraid to use as a backpack because of it, and the saxophone is weak to get the most compressive force in the vertical direction. It's a shame that I cannot upload a picture for the next customer who intend to buy the same item.
On the surface, it's easy to get scratches and metal parts of the case is already gotten much scratches in the manufacturing process and bent inadvertently.
