Cutter Maintenance:

When you notice the shredder is experiencing difficulty shredding, or gets jammed easily, then it's probably time to oil. If you use your shredder occasionally, then oiling your shredder may only be necessary every two months to maintain good performance. If you use your shredder a lot, however, then your best practices are to oil your shredder every time you empty the waste bin. Get your shredder lubricants by clicking here.

Connoisseur Experience By D. Spade

Best Shredder EVER

My husband and I were looking for a shredder that would shred cardboard. This is it! Now it's not the fastest shredder you'll find, but it's a beast for shredding paper or cardboard. Why, you may wonder, would someone shred cardboard--well, what do YOU do with all those pack boxes? I will let you in on a little gardening secret. If you've ever put together a compost pile, you need greens, like grass clippings, and browns, like dried leaves. The problem is, when it's grass clipping season, you don't have dried leaves. Shredded cardboard makes a great substitute. Our compost pile is roaring! Happy gardening and happy shredding.

Connoisseur Experience By Tom

Great for making compost from Amazon boxes and Junk Mail

Love this shredder. Have only had for a few weeks but it has surpassed my expectations so far. Bought this shredder mainly to reduce our garbage waste by recycling old boxes, newspapers and junk mail. It easily handles double-folded cardboard. If you buy for recycling purposes recommend buying this Box Cutters so as to make breakdown easy.

Connoisseur Experience By Mike

Cuts Cardboard Like a Champ

Bought it specifically because of other positive reviews here. If you're anything like me and have to deal with a seemingly endless stream of amazon boxes this device is excellent at gobbling them all up. It handily shredded the box it shipped in and the product box. So far so good.

Feedback on shredder

It was excellent for the most part. I am very happy with the shredder and its performance. However I had a question that I emailed to your Customer Service Department but never got a response. I wanted to know how often I need to oil it with the sheets.

Bonsaii Shredder

This shredder really shreds cardboard as described. I have been amazed on how well it shreds even really thick cardboard. I would definitely recommend it!!

Good Machine

This is a good unit. It does not overheat or jam easily and was easy to set up. Other comparably priced machines have had to be returned. Our only reservation is that it does not easily accept a bag for catching shredding. When the cabinet is full, it needs to be dumped into a waste container which can be a messy operation.

Great purchase

This shredder is working great. It is very quiet and shredding paper and cardboard just as expected. The best shredder I have every owned but I usually purchased cheap shredders that just never held up. This is worth the money spent.
