The device has a very fast and the manual is actually unnecessary because the operation is completely self-explanatory. I have not had experience with document shredders and was therefore surprised by the enormous volume but - in shock almost the bird has fallen off the shelf. Definitely not a device that you should use during the night. His work is done but reliable. Paper is fed straight and cut into strips. And unfortunately this is the point on which I have not sufficiently informed me before buying: the strip-cut. This has relatively little to do with Shredding - with some patience, everything can be put back together and depending on the direction in which the shredded paper was printed, can be even whole sentences or table rows read. That is not my idea of Shredding. The tray is (for strip-cut) too small, since the strips are still very bulky and not well coincide in the bucket. After a few pages of the bucket is almost full and should be emptied. In addition, the strips cover quickly the integrated tray for CDs and business cards. The device works technically sound, but not my idea of a paper shredder. I buy a device with particle cut.
