My primary goal was to chop up the documents as possible unrecognizable. And if I already DETERMINED me a paper shredder should control at least security level 4. What use to me 10 x 40 mm large snippets or even strip the yet to be made recognizable with a little patience !? In this price range with 4 x 10 mm large areas there is no reasonable approximate device.
The destroyer is structured in 3 min and performed for over four weeks his work without flaws. (2-3 times a week about 10 leaves).
I do not think the device is designed for continuous use in the office, but there are also devices in different price classes.
