I can only warn everyone to buy this clock. with me it was three days, then one could no longer analog clock adjust. also via radio, nothing more could be controlled. even the watchmaker could not help myself. I think it was an open especially as the clock on Wilder Mann cell phone accessories sold and is afterwards not to prosecute for the grant. To me it is also unclear how Amazon offer such product. so is Amazon provides a platform for fraudsters and stores the option item with obvious defects through third-party still going to be.
