The delivery took a little (approximately 1 week) because the traders in Luxembourg is resident, the price of 5 blanks, however, is very good and there were no shipping costs, when competitors Sony, there are the same number of blanks with selbiger size for just 30, - Euro. The blanks themselves so far I could not find anything that would not work, had initially described with a Full HD Video and rewritten Erased and again and again ... deleted, it is not an error occurred. Deleting walked me almost too fast because my burning program initially 50min indicated by less than a minute, the disc was ejected and was again empty. I use a LiteOn iHBS112-115 internal Blu-ray 12x burner, which it also is at Amazon for a really good price.
