I dont think that you can excuse a company ,or a model,(or a maker) saying that an average unit used in a tes,was substandard..what you are saying with this, is that QUALITY CONTROL is substandard, and that in itself is a negative review ...If you are trying to say that the Bins are THEORETICALLY good in their conception,you have a point ,but this doesnt translate in quality,except by careful implementation ..Or luck..
Charles from ZEN RAY said ,in some part of this forum ,that ZEN RAY has now their own facilities in China,and production as well as design ,are their own..This is of course recent news ,and does not apply to the ZEN ED2 that was reviewed in the Allbinos site...I think quality control sub-standards are the reason ZEN RAY wanted to move away from the previous source..If this the case We might see more and more differences between ZEN and other brands in the future(like the new Prime HD)
