The first OK the rest of scrap!

That you can rely on nothing more, showing me the purchase of these blanks. I have always bought Memorex blanks and was happy with it. Now I've caught a lot in the first obviously were still okay, the rest is junk. I initially wondered why the drive has not detected a fault and thought the torch, until I have found that the color coating of the blanks on the edge is wrong, and that clearly defective and evil. I have complained at Amazon for a good quarter and hope to purchase price refund. Should we in future check each blank? - Memorex no longer comes into the house to me ...

Addendum 27.03.2013:
Not only these blanks no longer come into my house, even with "ZBP Media" I will basically no longer order. After the blanks - added about three months after the purchase (because who already checked all the blanks immediately after purchase) - had complained, I was asked by ZBP Media that you return the defective blanks. I am then traipsed to the post office and have returned the crap. On a clear statement of ZBP Media I wait for about 3 months, until today. Even after I switched Amazon, I get "automatically generated e-mails" from ZBP Media is where I told a flat rate that the firm enters into (based in Luxembourg!) Only once a month repayments. At least a clear statement on the part of the seller would have been appropriate here. So you do not treat any customer, especially after you have asked the customer to return the defective goods. ZBP Media died for me - Stay away from this shipping store!
