There was no central piece in the packaging that connects the back cover with the front cover, resulting in all the discs being loose when I opened the case.

I have burned over 500 of these, maybe 1-2 have turned out bad, in which well-known company about half of them were bad in the 50s.

In the first 16, 12 had a problem with recording and became useless. In the remaining 4, the recording was done properly. I preferred another product to complete the task. Also, it is not in a cylinder, so when you open the packaging, it is loose

They did not present any problem to me. They are just DVDs. Out of the 50 pieces in the package, 2-3 of them got burned when I was writing them, but I think it's because of my recording medium as it has also burned other brands of DVDs.
