Never mind the current problem, here's what's going to happen very shortly. The catches on the case will break off, and the foam insert inside will get lost. Every time you open the case 93 pieces of Chinese cheese will fall onto the floor, and you will need to reach for the beta-blockers.
I know this. It's happened with both my socket sets and also my SDS percussion drill. I think that the plastic cases may have been designed by the very same spiv who came up with the battery compartment covers on our remotes.
