A metal pin was performed in a wafer-thin plastic frame, which has been exposed at each ignition of a very heavy load. The fact that this part had to break sooner rather than later, you can see him.
I do not know if that was konstuiert as predetermined breaking point for planned obsolescence intentionally or if it was an impressive misconstruction. Anyway, it's too bad about the otherwise beautiful device.
ADDENDUM:
I'm sorry that the created carefully, meaningful, detailed picture of the rickety plastic inner life that I had attached to the review, is not displayed.
