Query: Defective

Microsoft Windows Vista Home Primium FULL VERSION [DVD]Part No. X12-2416-02 DVD was warped! Additionally the labelwas printed off center. It vibrated. It was totally unreadable.It came in a big plastic box - not a DVD case nor a jewel case.The box had "Made in Puerto Rico" printed on the side. For$227.97 ($218.99 + $8.98 shipping) one would expect a usableproduct.If I'm to believe this product was indeed manufactured inPuerto Rico; then Microsofts' Puerto Rico operation lackssufficient - and as far as I'm concerned any - qualitycontrol. Be WARNED! I can't believe this was the onlyphysically defective DVD Microsoft ever produced.Since my purchase I called up Microsoft and they replaced my disc for free. At least they back their product. Thanks.
