Got one of them for free in my Lacie USB DVD +-R drive.
I think the name is Cyq've. It is a Ritek G04.
Made an unreadable DVD with it, but that's more to do with the drive being faulty than the quality of the media. I also got some LaCie DVD-R discs in the bundle, they're Ritek G04 as well.
And again, made an unreadable disk.
The writer was unable to read what it had just written - I returned it for a replacement, the supplier agreed it was faulty, a new one will be here Monday. Then I may be able to write some good LaCie DVD-R discs with it.
