If you want to buy a shredder, you have to look at its performance. Cheap shredders can have a paper jam. Office supplies should therefore include a paper shredder with a high sheet capacity.
If you buy a good but cheap shredder there is only a feed deficit. However, most shredder tests recommend models with a separate opening for plastic and a second cutter. With these you don't have to worry about paper jams.
In addition, high-quality micro shredders not only shred paper, but also staples and paper clips. As a result, you do not need to remove small materials before shredding. So you benefit from time savings. A recommendable feature is the automatic paper jam removal. Unfortunately, this is rarely found even in high-priced models.
