Since copying of music CDs on such devices as the Sony RCD W 100 simple and is carried out in better quality than when burning via the PC, the entertainment industry has (unfortunately) painted such devices many years ago from the production line.
CD-R Audio blanks there are thankfully still buying, but very limited. Apparently, the demand is not big enough.
In Austria, more precisely in Vienna market can hardly be obtained in which the major retail chains such as Saturn and Media - regardless what brand.
Finally, I landed a 10er brick Verbatim and had 7 !!!! 10 piece throw - a bad joke. I thought my Sony is in the bucket. So I got myself out of Germany this 25iger bricks from Maxell and lo and behold - everything easily. The recordings on CD, cassette or vinyl are top notch. Only about 2-3 blanks fail after error message. That is, considering the current possibilities and technology developments, still questionable, but acceptable for my recent long-term experience.
On the whole, therefore 4 stars.
