Ultra-fast delivery, no problem there. But I had a series of discs to burn with my recorder Sony RDR HX 910. I have wasted five of the 25 contained in the box "dirty disc" pattern. I have a recorder offending my time, but I bought a box of 25 DL discs of the Verbatim brand, certainly more expensive, but no strike after eleven burned discs. Do not hesitate to pay the price, you will lose less time.
