Once I have a Peach document shredder for strip cut 7 mm, I bought the same brand of this device with the cross-section, because the amount of waste so compact (and safer) is. After it has "processed" several years bank statements today, I can certainly give a positive verdict. However, it is so that the stop of the unit in continuous use occurs earlier, however, the machine has to work at cross-section much more. The device attached pattern sheet let oil as lubrication for traversing is not a bad idea, the specified item no. is specified for ordering, but the "where" is missing. It is recommended to oil tank after each flush. As with my previous device, it is not conducive when sheets are inserted at an angle, which is safe for other brands too. Overall, I am very happy; for larger amounts of data you just need some patience and breaks. In size, the device fits on the bookshelf, so that it is available at all times.
