The "zero star" does not exist. Too bad, it would have had to invent ... The radio side connector is not the correct size. I tried to change it to destroy it. I then realized that the connections do not correspond to what they should be (compared to a fit of origin!) Luckily it does not fall! I am far from zero, I spent 35 years troubleshoot mainframe ... for the world's leading manufacturer, American not to mention it! I wanted not to be rude, but never mind: it is a **** m to avoid at all costs. I do not know whether that assessment will "censorship." PS I'm pretty heavy user of Amazon, and have almost always been satisfied.
