I have these. Only problem is that I have hardly time to do some testing.
I might be able to do some testing next weekend.
What I can say is the following.
Bonding: GOOD but ugly looking like Ritek
Smell: Quite Smelly
Overall construction quality: Looks ok.
video playback on my Philips dvd player and ps2 was fine. (Had to use one as second disc, because I ran out of other media.)
Also I personally feel that support might be quite drive dependant on this media.
