Query: 40% Failure Rate

This has nothing to do with the quality of sound that was recorded on the CDs but with the fact that half or more failed. We were sent this brand of music CDs as a substitution for the ones we ordered. It took 2 spools of 50 CDs each to get 60 CDs to burn at all. The ones that did burn played OK but we noticed what looked like a lot of flaking in the CD material itself.Bottom line - We will not use this brand again nor do we recommend it at all.
