I got some of these a while a ago and the recording and playback was ok. I have noticed the price has come down quite a bit on these and would consider buying them again. The ones I bought are packed in 100 pack cakebox and they have a mixture of mid codes. TTG,MCC and CMC. They are also oveprints. At the time I didnt buy more as the price between them and other discs wasnt big enough to warrant using them.
I have noticed that these are now being sold for 14/15p each at that level I think may pick up a pack next time I need discs.
