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.

It really shreds!
I really like the Bonsai shredder I ordered. It feels substantial, not just a 2 lb. cheap shredder. It works beautifully. My instructions say to use a lubricant sheet after 2 sessions of shredding that fill the inside. I especially like the 240-minute continuous shredding option. I'm shredding lots of old documents, and this shredder is just right for that task.

Super Quiet
Super quiet, super easy to use, makes super small pieces

good machine i like it

Bonsaii paper shredder: 4S30.
Good. It works as expected. I can not complain.

Bonsaii 4S30 P-5, Incredibly quiet shredder.
Wonderful. Incredibly quiet for a shredder, especially since it is P-5 High Security Level. So surprised; quiet, great build quality, and nice white color with tan trim on the sides. Looks much better than the old black shredder it replaced. Purchased it on sale, but worth every penny, even at full price. Buy it, you want be disappointed. Bonsaii, you have a new customer for life.

I really like how small the paper cuts, all the features, size, and shipping & packaging was nice. I bought the oil to use and look forward to this machine properly working and lasting a long time.
