Victor,
We've had one personality module break on VisiPatch. I've had our techs start supporting the rear of the cable during the test and any time the module is plugged into the C-4. I'm not sure if this is a good solution, but we haven't had another problem, and this module has already outlasted our previous one. I wish they would design a true VisiPatch module with the reversed patch cord. There's just so much weight on the back of the cord with the current design I have never felt comfortable with it.
