Apart from holding the product delivers what it promises. The hard drives (3.5-inch) fit very closely and are therefore protected against sudden slipping out of the case, so to speak. The lid is a foam buffer which additionally stabilizes the hard drive against uncontrolled sliding around in the case. The lid is connected to the rest of the case is not about a hinge or the like but only a kind predetermined breaking point, but this makes a fairly stable impression and also shows previously no defects (no demolition, tearing or breaking so far).
The product is used in our company for the storage of daily backups of hard drives (backup via docking station) every day and we are completely satisfied.
