Amazon replaced it with a second unit after the first one had issues with the "Wake To" button. I could not choose between iPod, Radio or Buzzer to wake up to. The second unit arrived and it worked fine for a few days and then the "Wake To" button stopped working again. Too bad, because the rest of the functions are OK and its sound is very nice. I ordered a full refund. What I can't complain about is Amazon's service, they are the best, they deserve 10 stars!
