Noisy and not particularly for many hours of operation designed.

The shredder I bought 13 months ago, and disposed of a few days ago.
The unit has had to deal with just about 10-15 leaves per working day in this period. These are probably less than 5 hours of operating time.
The rollers tend to very quickly (depending on the paper manufacturer) add - and then form firmly compacted paper leftovers, can seize (despite regular cleaning and frequent empty front-and back driving) burst the weak designed Kuststoffteile, and the screw mounts.
The unit is very loud, and he does not begin to shred the advertised 8 sheets at a time. Already 3 leaves are a real Herausvorderung.
