That's true. People want crap, they get crap. :-)

In Germany, we only get the purest power made of highest
quality electrons, 230V 50Hz 24/7/365. :-) Note that I'm
running this power supply for more than 7 years now - the
SAME power supply.

That's right. If you have the chance, monitor your power
outlet, e. g. with a long term peak monitor or a scope
with battery backed up memory, just to make sure the
requirements of the PSU are met.
