For a time I would always seek out these Sony recordable CDs, regardless of price, because of confidence in the brand. However, after what I considered a rather high level of faulty/unreadable discs, I decided to try out various other brands (including low-priced supermarket own brands). All without exception yielded a much lower failure rate. Not only that, the Sony discs also recorded at a noticeably slower rate than any other brand I have tried, considerably slower in some cases. I will not take a chance on them again.
