Query: poor quality

I returned this item and took a big hit on restocking fees/ shipping, etc, so i am a bit bitter. i should have got it from amazon. why did i return it?1) the build is poor quality plastic.2) the sound was horrible. i could not get any decent radio stations. (i live near downtown) even the cd player was of mediocre quality.
