Some people have said that the Ritek CD-Rs are decent quality. However, my experience with their DVD media (and many others had the same problem) is that while the media would burn fine, once tested, the DVD media shows rapid degradation, to the point it is unreadable in 6 mos-1 year. Ritek has very dodgy Q/A, and no warranty on the DVD media (I would assume there’s also no warranty on the CD-R media, too), so I personally would avoid it. I would get Taiyo Yuden CD-R media, as for just a few $$$ more, you’ll get guaranteed quality. Of course, Verbatim CD-R media also carries a lifetime warranty (like Taiyo Yuden), so you could try that. At the very least, buy some CD-R media that carries a lifetime warranty. If a company doesn’t give that kind of warranty on that media, good rule of thumb is NOT to buy it.
