"platinum dvd+R DL" quality check

saw somewhere a picture of “platinum 8x speed 8.5 GB”,
has anyone information (link?) about the quality of those discs?

They are either Ritek 8x or CMC 8x media.
Better than Ritek’s 2.4x media, but most likely not as good as Verbatim’s are.

Exactly, a waste of money.
