BONSEN S3105 24-Sheet Cross-Cut Shredder

In this bonsen s3105 24-sheet cross-cut shredder review, the BONSEN S3105 earns the number eight spot in our 2026 heavy duty guide and the label Best for 24-sheet manual batches. It is a corded, manual-feed cross-cut machine that takes 24 sheets of letter-size 20-pound paper per pass and turns them into P-4 pieces measuring 4 x 35 mm, or 5/32 x 1-12/32 inches. The price is $299.99, and the Amazon listing carries a 4.6-star average from 988 ratings. Buyers who empty a shredder by hand and want a quiet room get the most from it, since its 55 dB rating is among the lowest in this group of ten. It weighs 43.3 pounds and measures 11.6 inches deep, 16.7 inches wide and 25.4 inches tall.

The headline feature of the BONSEN S3105 is its 40-minute continuous run time, which means you can shred roughly 5,230 sheets before the motor needs a 60-minute cool down. In practice, that is enough for a full afternoon of clearing a filing cabinet, though not for an all-day purge. Its cross-cut blades produce 4 x 35 mm particles rated P-4, a security level suitable for documents holding personal or financial data. Meanwhile, the 9-gallon pullout bin swallows about 650 sheets, so you empty it rarely compared with a 5 or 6-gallon model. At 55 dB, the machine runs quietly enough for a shared office or a home workspace near a phone call. The three-button panel (Power On, Forward, Reverse) pairs with LED lights for power, overheat, overload, bin open and bin full, and casters let you roll the 43.3-pound body aside.

At $299.99, the BONSEN S3105 sits in the middle of our top ten, and it justifies that price for anyone shredding mixed materials a few hours a week. By contrast, the auto-feed shredders ranked above it run 60 minutes without stopping, which suits anyone who wants hands-free work. However, the 9-gallon pullout bin and the 55 dB noise rating give this manual model an edge for quiet, low-maintenance shredding. The catch is manual feeding: a 200-page stack goes in 24 sheets at a time, so patience matters. On top of that, the 60-minute cool down limits marathon sessions. Even so, the 4.6-star average from 988 ratings suggests buyers accept that trade. If you shred in batches and want a quiet room, this is the one to get, and the 1-year customer service warranty adds basic cover.
