Summary: the first unit arrived and the FM receiver was broken. i got so far as unpacking the speakers on the second unit and all the mounting scews were missing such that the speaker fell right out of the speaker box. am going to try one more exchange to see if i get a unit that actually works.
Summary: I bought the stereo based on the Harman Kardon reputation for quality and workmanship. I was disappointed to receive a defective product, however Amazon was more than accommodating in arranging a speedy exchange.
