I never doubted the quality of Verbatim CD used now for years. Never a problem, some even dragged without their case and still works at this hour, in contrast to some more discount brands! The 100 CD case is more difficult to find commercially. Amazon with whom I never had any problems to use it for years, we offer in addition to a very reasonable price in view of their quality in the long term and the error rate almost nonexistent during the engraving. These CDs can be read all CD players and of course may also consist of a storage system quite interesting for your various files. Amazon once again proved extremely reliable, I think that even this present their reliability is not really in question. The delivery has been widely respected. I never had any problems on that side, for that matter ... The article perfectly matches my expectations at a very reasonable budget, I have never hesitated a second to buy this product even on Amazon!
