Jim has a physics degree from MIT, as well as a Master of Science and a Ph D in mathematical physics from UCLA.
With his help, we tested how easily each shredder overheated, the maximum number of sheets of paper each model could shred without jamming, the noise level, and if it could destroy a CD or a credit card.
We've long recommended the Amazon Basics 12-Sheet Cross-Cut Shredder, which can handle up to 19 pages.
But it's been in and out of stock for over a year and is unavailable as of this writing, so the 8-Sheet model is the best option of those we've tested.
It can run continuously for 40 minutes before needing to cool down, only takes about five seconds to shred a single piece of paper, and has casters for mobility.
The Amazon Basics 6-Sheet is an affordable choice with a dedicated CD slot that is perfect for any home office.
This model also produced the least amount of operating noise of any machine we tested.
