Input: Consider Input: Simply put, out of the box it did not work, totally defective. Excuse me, the clock works and the CD door opens and closes continually. It just keeps opening and closing on its own, and does not play any CDs. What a waste of time and money. I should have checked its playability before I jerry-rigged the bottom of my cabinet so it would fit. The bottom of my cabinets are recessed. So I did all that work for nothing..
Output: negative
