Bought these Ridata discs a couple months back. The cheap price was attractive, but that's all I have to say about these disks. I probably get a good 25% of the discs burn correctly, while the remaining have piled up to an impressive coaster collection. Kinda frustrating whenever you're 10 minutes into burning, you get an error and the disc is ejected. I'd recommend a name brand like Memorex instead. Hardly had issues with them.
