Equipment properly performing the function for which it is designed if it destroyed documents in sheet, for a reasonable price. I bought this camera with a bottle of lubricant "Fellowes 35250 Lubricating oil for paper shredders" I use intensive destruction before each session. Five sheets at a time does not seem possible because with two leaves the drive motor of the cutting tools slowed sharply. Remove staples if one does not want to prematurely damage the unit. In sheet (one sheet after the other) the device works more than 30 minutes before the motor thermal food safety is cut. The user will ensure frequently empty the trash to avoid the jam due to the return of the strips cut in cutting tools and to identify the cut strips that wrap around tools taking the precaution of unplugging.
