It looks sturdy. It fit a lot of things, but due to the geometry, moving from a toolbox-case to the one that is more compact with greater height, I needed >15% more volume than my old one. I don't know if it will withstand over the years, but for now, it looks solid. The latches are very tight, so they provide durability until they loosen, and the hinge that is stated as metallic is actually plastic with a metallic core. In other words, it all depends on how long the plastic lasts, considering everything is as strong as the weakest link. If one by one "link" of the hinge starts to break due to impacts, it's our fault, if they soften from use and give in, then it's their fault.
The handle is very comfortable, as well as the movable shelf it has, which provides access to the central space and space for bulky tools (e.g. hammers, angles).
