Well, I must say after reading all of the ZM threads it is with trepidation that I await my tomorrow scheduled delivery of my own ZM. I hope all of these unfortunate OPs who also bought a ZM are exceptions to the PRS QC standards and trust that PRS will make 'em right. However, I would have to admit that if I received a "less-than" new ZM I too certainly will be disappointed. I'll know tomorrow. Fingers crossed.
