A carelessness ended the life of its predecessor (too many sheets inserted at once, was no longer flottzukriegen), so a new device matured. I got me through the various offers and the related reviews read me and then for technical and also for aesthetic reasons (is slim and looks great in the office) for this device chosen. And the decision was correct: The Powershred M-7C is quieter than my old unit, although he has a more powerful engine to some, the problems become even up to 7 sheets at once zershreddert [probably even more, but I am cautious ;-) ]. It is well made, makes a very stable and high-quality impression. Also the capacity is more than adequate for my one-person office with not a lot of paper waste. I am fully satisfied and would recommend this device without hesitation.
