Query: Highly Defective; Unable to Burn...

1 among 8 cd's have burned successfully.My experience was good with Memorex cd's earlier; but unfortunately this time it was 100% worst.These discs are really crappy and doesn't do the work.I would never ever prefer Memorex in future again.I hope Amazon stop's selling this particular product for others and ensure that Amazon's service is the best; as always.Thanks,Kesava
