Review on MAXELL Normal BIAS UR-90 (15-Pack): Standard Size Cassettes for Superior Audio Performance by Chris Horton

Poor quality. Brand new tapes have a damaged tape edge. Of the 10 brand new tapes that were just taken out of the box (before being used in the tape recorder) I had 2 faulty ones. The tape edge (visible on side A) is wrinkled, resulting in poor sound on the left channel. It was incorrectly cut or wound at the factory. Very disappointed as there is such a limited choice of new audio cassettes these days.
