For me this has been EXCELLENT media. It's cheap and it burns at 12X (about 6:39 for a complete disc). All of my Ritek burns have been excellent, and all with low PIF's. The PIE's are a little bit high, but they seem to have improved with B7T9 making it a good upgrade for this media - at least on my system.
That said, I heard some rumblings a few months back that Ritek was having problems maintaining the consistency of their media. I'd guess that was just teething problems bringing new equipment online to meet demand, but I don't know if these problems still persist or not, and I don't know if these problems even applied to the 8X R03 media.
In the bundle of 50 that I purchased, I have seen no issues at all and would not hesitate to buy them again. However, your mileage may vary.
The Riteks are one of two brands that I like. The other is SmartBuy Prodisc R03 8X media. It too overspeeds to 12X and it too provides me with excellent scans. The PIE's are extremely good - even better than the Riteks. The PIF's are generally slightly worse, although perhaps I can't really say that anymore, since they seem to be performing better after the B7T9 firmware upgrade and the B7L9 "cleansing". Again, YMMV.
In any case, Good Luck with your purchase tomorrow!
