Well perhaps some of the Dyson "experts" here who don't like them could

I believe the original fault was a poor grip on Dyson's shiny silver
cable, so the tension wasn't being relieved by the outside clamp and
was still pulling on the conductors. On some of them, the cable
between the strain relief and the terminal block was simply too tight,
owing to a millimetre-shaving exercise in the factory.
