Query: INFERIOR QUALITY CD'S

THE CD'S IN THIS SERIES ARE VERY INFERIOR...I HAVE TRIED THEM ON MY EXPENSIVE BOSE SYSTEM, AS WELL AS, IN MY CAR STEREO...THEY SKIP AND ARE NOT A GOOD QUALITY.I TELEPHONED THE 800 NUMBER ON THE BACK OF THE BOX AND THE COMPANY WWW.PENTONOVERSEAS.COM IS NO LONGER IN THE RETAIL BUSINESS...SO LOTS OF LUCK GETTING A CD REPLACEMENT...THIS WAS AN EXPENSIVE 4 WEEK SET AND I AM NOT HAPPY ...$49.99 DOWN THE DRAIN...SOME OF THE OTHER PENTON PRODUCTS WERE WELL MADE AND GOOD QUALITY, BUT NOT THIS...HOPE NO ONE ELSE HAS GOTTEN TAKEN
