Have so far about 50% of CD's burned CD's are so far in order. Even rewriting worked well. With 80 minute run time I'm a bit unsure. When a CD I could describe only 70 minutes, the rest was me "thrown out". Because there is a lot of work, the title "contemporary" to compile, I have become cautious and go just behind 70 minutes to spare me a renewed eviction. Possibly it was only a "single case" what a should not deter, to order the CD's. Have been a few "brands" tried, whether or not writable. Guess you is well served by the product.
