I am assuming that that product that we received in advance which the previous owner had NEN has sent back to any of repair attempts, along the lines of no one will ever notice. However, I expect the seller that he products which he gets zurückgesand tested for defectiveness and not send implied. at least the function of "light" can check because he would have noticed that it is defective. So there's one of us 1 star, because fewer unfortunately not possible.
Incidentally, this was our last Trixi product the entire brand offers only by defects, faulty workmanship, and short-lived.
