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.

Awesome shredder at the right price!
I found the Bonsaii 4S30 shredder to meet my expectations. It’s shred size is great, too small for anyone to get any information. I also like the fact that because of the very small shred size, you can shred way more than a regular cross-cut or strip-cut before having to empty the waste bin. It is a bit slow, but is to be expected considering the P-5 shred size. Overall, so far, I am impressed with the unit. I hope to get many years of use from this shredder. If you need a new security shredder for your office, buy one of these!

Best Shredder Ever Purchased!
This is the best shredder I’ve ever purchased. Not only is it the quietest shredder I’ve ever used, but it is the most efficient at shredding whatever I put through it. Though it is only a 10-sheet shredder, I am extremely happy with it. I’ve had shredders that claim to handle more pages at one time, but they always seem to labor excessively with the 15 sheets they are rated to handle. This shredder handles 10 sheets with ease. However, the thing think that amazes me the most is the length of time that I can use it! It is rated at 240-minute run time. I have never run it that long because I have no need to run it that long. However, I purchased it because I wanted a machine that would run longer than I ever expected to need it to run. Though I generally shred fewer than 10 pages at a time and only run it 5-10 minutes at a time, I am admittedly no texting it to the maximum. Nonetheless, it has already proven to be of superior quality to another name brand that I have used for years. I have always worn them out with heavy-duty usage. Moreover, they were constructed with a much lower grade of materials than this Bonsaii shredder. Just open the bin, and one can see that this product was designed to last! Even the BIN is constructed of a high-quality plastic rather than a cheap cardboard! I want to emphasize the fact the power supplied by the motor in this model seem quite adequate to the task for which it is designed. It does not labor under heavy loads, nor does it have to keep reversing to handle varying loads. It simply shreds the papers with easy. I HIGHLY recommend this product as a FANTASTIC BUY for anyone looking for a replacement shredder who is tired of shredders that jam, break, or simply overheat in a short time. I have NOT had any of those experiences with this shredder yet. I have the highest regard for this product at this time. After I have used it three months, I would love to rate it again and see if it is still performing in a similar manner. My experience so far tells me that it will be!

Best Home Office Purchase!
This shredder has been a fantastic addition to our home office set up. After years of using (and replacing) a basic shredder, we decided to spend a tiny bit more money and buy a real shredder. It's so easy to use and safe to empty. This is a no brainer purchase.

Impressed
This shredder is much quieter than our previous unit and when it is done, the paper looks like kitty litter. No one is going to put that back together! It is smooth to feed sheets in series, and when I heard it run for the first time, I laughed out loud. What a contrast to the previous shredder! I can't come up with a con.

shredder
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.
