That's not nice. It's just cheap. At Cambridge Instruments the argument 
for going over to crimp connectors was that you found a lot less duff 
connections when you were putting product through final test.

The parts and tools were more expensive, but fault-finding and fault 
correction were expensive enough to tip the balance.
