I burned now 5 blanks and can not find anything negative.
I use this primarily as second backup solution for my photos (there are always more so, RAW Greetings) and have now also a first attempt behind me to burn the full HD holiday on the disc (as an ISO with the Prgramm ImgBurn) which works wonderfully. 3D is still pending, but should work well also.
My PS3 plays the BD without problems. The photos can be viewed from the BD from. However, this proves to be particularly practical, but what is more to the PS3.
The blank has a great price / performance ratio especially when one sees the GB / EUR relation. Here DVDs can not keep part.
I'm going to the blank sellers asking if there is a need: 5 stars.
