ah so great customer service! indeed the cable fails (2 times anyway) and they changed me every time
Caution: Do not operate elsewhere than charging: do not even try on the PC it does not work!
good after this detail another defect: abandon the system ventilation panels grids! the pins break (glued twice) and are unsuitable for open cars of several brands. So prefer a product type or another sucker
which therefore saves their note: customer service! ls are understanding and very reactive: KW-commerce thank you :)
