Tests from me and my friends and from third parties.( magazines and 2 stores and some other people. )
Error rate checked by me and the magazines and was very good. A lot of writers where used while the mags used mostly Lite On and PLextor drives we ourselves did some tests(mostly wses/cd-docter ) with LG 52x and 40x writers.
Shape was tested by magazines and I tested it rough.
UV tests are running at this moment. But older fuji media scored okay base on (own test and 2 test reports.)
Chemical corrosion was tested by a magazine and was okay but not as good as most other disc's.
Humidity was based on experience from my local store(BESS) employees and at this moment some people are doing some back checking on it.
