Most inexpensive shredders have a very low duty cycle, so they'll cut out or overheat if you shred continuously for more than a couple of minutes. That's fine if you shred a couple of documents at a time, but it's infuriating if you have a big box of documents that need to be shredded. Heavy-duty shredders capable of continuous use are bulky and heavy, which is a significant issue if you live in a small apartment.

Ah makes sense. I guess I just do it as I need to, since I don’t do the document buffering thing.

just burn em in a trashcan

I use a cylinder of wire mesh on something heatproof, in the garden.

Better than a cheap shredder by miles, and some nice heat that makes it pleasant in wintertime. :)

Domestic burning of household waste is illegal where I live, I would have thought it would be illegal most places in the Western world by now. Burn paper = CO2; shred paper = more paper.

It takes many hours to shred and not worth my time. I have a shredder for the rare cases I need something shredded NOW.

Even more fun is supervising a young child doing the shredding :)

Or a fireplace...
