F/U: The seller was deeply distraught about his error in shipping the wrong item and by my negative feedback. He took full responsibility for his “mistake” by refunding the purchase price in full and insisting I keep the erroneously shipped item “for free”. I can’t think of anything more that he could have done to rectify the situation. It turned out vendor has integrity and (absent any further problems), I wish that my initial critical evaluation not be held against him.
