Well, I have once gotten bad batches of Verbatim DVD+R even from Amazon (germany), and it was difficult to get them replaced, simply because they are selling that stuff but obviously don't have the personell that has some basic knowledge about optical media at all. So finally, the media was replaced by Verbatim.
My point is: when I buy Verbatim Azo+, I expect to get the highest quality availble on the market, no matter where they produce it or how much I pay for it, it is their job to ensure constant quality. If they fail to do so, they are not worth buying. I will contact both of them, Verbatim and xmediatrade, and see what they will say or do. I will post their reaction here if you are interested.
Btw, the reorder number of my spindle is 43550, is there any possibility to see if this could be fake media? I don't think it is, but I just want to be sure.
