The part is so cheap junk that you can not at all be described in words. The tones sound really bad, a loose connection was included. I bought at my Oxyd7 both a withdrawal and an exchange was denied. Would be repaired only if I had a nonexistent warranty card, aha. So when the goods of Oxyd7 is no guarantee expected, okay.
I have the part then screwed inside to schlampigst soldered contacts have touched. Wherever the part also comes from it is the purest and who botched the still builds the car need not be surprised when the box abfackelt!
