4.5 Good quality product Synister | 24/10/2008 | See all Synister's reviews (2) You pay a little extra but these discs are top quality. As the previous review states, there are no compatibility issues with these discs. I have tried other brands but always find some problems. I use a Mac and some discs make an awful noise in the tray but these run sweet. I also send discs out to clients and customers and have had no problems or returns. Prints are sharp, colors are accurate and ink dries reasonably quickly.
