Query: CD Issues

I purchased this clock radio because it seemed to include all the features I need. It did not disappoint me until I attempted to use the CD player. The CD player in the first unit I received was very noisy and made strange clicking sounds. I returned this unit as an exchange. The second unit I received would not play a CD at all, so I sent it back and received a refund. Overall, I am very disappointed in the purchase, but Amazon did guarantee the product and handled the exchange and refund very efficiently.
