Query: Excellent purchase

We had previously purchased an under-the-cabinet radio/cd player but the first week the cd door wouldn't open. I thought I had broken it, but after reading other reviews of the same model, I found out that it was a defect and I didn't break it. I researched other brands, and found better reviews of this model. It has been a good purchase. We get many more channels on the radio and the cd player has not had any problems opening. The sound is excellent and we are very happy with it.
