I brought this machine back in June for the office. It was very easy to put together, it literally took 5 minutes. As you can see, we are using it. It's strong and we have shredded at least 10 file boxes full since. Sometimes the paper does get stuck, but I truly believe we are sometimes put too much paper to shred at once. No need to remove staples before shredding. The only real problem I see, the bin that hold the paper should be a little sturdier. But for a small office it works really well.

    If you have been using those $80 shredders, this thing will amaze you! It does one thing, and does it well. In a week, I have shredded three garden trash bags of paper, including over a dozen old cards. No jam or stopping from heat issues, yet!

    .  I was using two old & cheap Fellowes shredders that had a 10 minute run with 60 minute rest rating.  They would slow me down jamming and overheating.  Then, one just failed and the other started sounding like the motor was giving out.
    . This Bonsaii has already done 3 times the shredding in less than half the time!  I am about half way done and expect this shredder to keep going for years.
    . The 18 sheets warning is probably for #10 paper. I am shredding thicker stock, usually old bank statements and bills. I'd say about 10 of those sheets is the limit, but my old "8 page" units could only do about 5 of them.

    Pros:
    - It is relatively quiet.
    - It just keeps going.
    - It shreds two credit cards side-by-side.

    Cons:
    - The basket was broken just above the clear plastic window, making removal and insertion feel a bit flimsy. I went ahead and taped the break, because this thing is so much better than what I was using, and I wanted to get this shredding job done. I have started an email with Bonsaii to see if I can get a new basket.
    - Nothing else, really...

    Gripes:
    - I just bought this for $169.99, and 10 days later it has dropped to $142.79. Do I go to the trouble to return it and reorder it just to save $27.20 (~16%)? Maybe... I need to get this shredding done and this Bonsaii is doing it (:>)

    I would suggest this unit to any heavy shredder in the home and small office environment!

    I have only used this once since receiving it yesterday, but I am so well pleased by its style and function, I had to add my review right away. I have a smaller version by the same brand/ company that shreds fewer pages and doesn't have wheels. It is okay, but noisier than I hoped and doubted it could manage the amount of shredding I need to tackle, semed a bit stressed after a short session of shredding and therefore I have only used it a few times. I decided to try this upgraded model. So far very pleased with my decision. The pages feed smoothly and quietly, more than any of the other shredders I have used (one my husband had that we gave away before we moved was not too noisy but was not a cross cut and it was a bit heavy and cumbersome) This is much lighter and the wheels area grat benefit. I love the pull out drawer and greater capacity it holds with the window to see as the the bin fills up. Plus I can open it to spred out the pile and push it down to keep the paper from blocking the blades and allow.it to hold more and more paper. It handled a full shopping bag of bills, documents, mail etc. in about 20 mins. Probably could have taken even less time, but I wasn't doing a full 18 pages each time. Love that I could do a variety of paper types and not have to unfold everything. If a small portion of a smaller paper didn't completely shreed it stopped and stayed where I could easily flip and feed again without jamming. There was no jamming, but I feel the reverse switch feature would handle if needed. And no smell of a motor being overly worked. This model makes this chore a breeze., almost fun even. Highly recommend so far, but I feel confident it will hold up.

    I'd been limping along with a decades-old Fellows shredder until a month or so ago when I decided to do a major junk clean up around the house. My old shredder could not keep up with everything that required shredding and was starting to sound like a freight train, so I decided to try out this Bonsaii shredder. The first week I had it, I shredded about 10 pounds of junk mail, with no overheating. This baby worked like a charm, and was even relatively quiet about it. Now I use it daily to shred any junk mail I get. The shredder easily handles 18 pages at a time and slices the paper into nice, neat little pieces. It handles staples like they're not even there. Shredding credit cards and the like is a breeze. Unlike with my previous shredder, I do give this one a few drops of oil every other week, which I hope will keep it running a very long time. The only downside I can think of is not a big one: putting a bag in the shredder's bin does not always allow the bin to close properly and the shredder will not work if the bin seal is not just right. I've tried putting the paper collection bag in different positions, but I've yet to find a placement that consistently works. So I use the shredder without a bag and dump the bin into a recycling garbage bag when it gets full. All in all, I love my new shredder!

    Size: 1 8 Sheet Cross Cut 6-GalVerified Purchase
    Many years ago I purchased a Rexel 5-sheet shredder that has performed well. My requirements have changed, given the quantity of cardboard one accumulates from online shopping. Careful research suggests that heavy duty shredders aimed at the SOHO market should be capable of shredding cardboard. Indeed, the Bonsaii website states this as a capability for the C149-C. The next decision was to choose between a micro cut and a crosscut. As security isn't a concern for me, but capacity and speed of throughput are, I believe cross cutting shredders are a better choice. It's a pity that there isn't a common standard for shredders stating how long a model takes to shred a single sheet of A4 paper, and how long when the maximum rated sheets are shredded.
    Since I received my C149-C I have shredded about 25 kg of paper and cardboard - mostly cardboard. I have had several sessions which consisted of almost continuous use, and the overheating light has never come on. I have shredded paper, magazines and various types of cardboard. It seems to me that if the material to be shredded passes through the 5mm entry slot without being forced, it will shred. My old Rexel sounded as if it were straining when near its maximum capacity, and not infrequently jammed. The C149-C is quiet in normal operation, and a passing a thick piece of cardboard through it does change the sound of the motor, but it never feels as if it is about to quit. So far, it has tackled everything I have thrown at it.
    The build quality appears good, with a pleasing heft to the motor unit. The removable box for the cuttings slides in an out reasonably easily, although sometimes it needs an extra push to seat properly so the 'box is missing' light goes out. I purchased some 23-28l plastic shredder bags from another manufacturer, but found it isn't worth the hassle of using them to line the box - inserting the box and seeing how full it is become more difficult. I now don’t line the box and simply tip the contents into a bag when the box is about three quarters full. With a modicum of care spills are avoided and I repeat this 3 times before the bag fills up.
    I also bought lubricating oil and using it every second load, given I am shredding cardboard covered with sticky labels and adhesive packaging tape.
    Strangely, the one material the C149-C isn't so good at shredding is the brown paper strips that Amazon uses as padding in its shipments. The reason is this paper tears easily. Having been scrunched up, it can slightly jam as passes through the entry slot. whereas cardboard is pulled powerfully into the shredder, this paper simply tears. The other minor annoyance is the slot is wide enough to take A4 paper in portrait orientation. The 22cm "M1" envelopes Amazon uses only just fit, and the "A3" envelopes at 24cm need to be cut in half.
    As you may gather from the above, whilst it is early days, I am very pleased with my Bonsaii C149-C, especially as several competitors cost considerably more.

    I had a cheaper shredder but the amount of shredding I do I needed something bigger to do the job. Well I am not disappointed with my purchase, this machine is a work horse. Hasn't heated up or jammed on me once. I use the recommended lubricant sheets before every use. I would recommend this and in future would order it again.

    Unwrap it carefully. Buy the oil but not the bags.
    I am trying to be as green as possible and in early retirement I have been shredding a lot of old work related documents as well as my daily i newspaper and as much of our lockdown delivery cardboard as fits through the shredder.
    First impressions: It arrived as predicted within 48 hours and was well packed and Undamaged.
    As described by others the Castors look fragile and are not free running even after lubrication.

    It was bought to replace well used (10yrs+ ) but jammed and burned out high end domestic Fellowes machine with a easy to empty basket. ( see comparison in photo ).

    I am using the plastic bag that came around it in the box, it was also supplied with a single bag inside as well. Buying commercial see through polythene shredder bags will be convenient but they cost 16p each and won’t biodegrade.

    I oiled the cutter blades before use.

    Performance after filling one bag to brim:
    Noise - much, much less noisy than my old machine and more pleasant pitch - you could work in the same room.
    Capacity- 20 mins continuous use including up to 16 sheets of professional magazine shiny paper, several i newspapers torn in half lengthways, amazon cardboard book delivery cartons folded double thickness to full width (22cm)
    I didn’t try it on copier paper.
    The cooling fan comes on while in use but at no time did it run over after finishing shredding an item.
    As reported by others, for security purposes, the chads are wider than other machines but for composting this does not matter. I suspect this also the reason for its quietness and speed.
    It cross cut the newspaper much more effectively and therefore the shreddings sat down in the bin more easily. As a result I got a lot more in the bag than my old machine.
    I try not to compact the shreddings as that defeats the speed of compost making.
    Speed: for home use it was comparable to the old Fellowes and for a once a day session I am content
    but you cannot fill an auto feed and walk away.
    There was a slight delay on both starting and starting to reverse - this might be a good thing. It stopped 2 seconds after the cutters cleared. It stopped automatically on the first fill but I am not sure if that is a feature.

    Ergonomics: it’s lower than the old machine but the slot is same distance from the front. This made it more of a strain to feed it while standing but it’s shape and size and the (careful use of ) the castors mean it would be ideal for sitting under a desk.
    The bag sits over the rim at the back and sides and I did not have a significant spillage, the clips at the front are a bit fiddly but once you master the technique it clips in and prevents leaks at the front.
    I would not want to tip the shreddings straight from the bin into a plastic bin bag as the plastic felt quite fragile and the rectangular shape would not fit easily into the bag for a second fill and protruding plastic lugs would tear the bag. But transferring shreddings form the transparent bag to another bag was pure dead simple.

    Reliability: no comment

    Excellent first impressions. If it lasts then it should be more than adequate to supply my Allottment with brown material to go with the kitchen waste and grass clippings

    This is the second model of these I have bought for my office and have been more than happy with both. The unit says is can handle 18 sheets at a time - but I feel that unless you are only using 70gsm paper, the correct number would be more reasonable at 7 sheets (80gsm). The cross cut is a good feature for destroying confidential items and the box is easy to remove and empty, with a visible window to see when needed. The shredding is quite quick and although a little noisy, on stays on for a short while due to the automatic cut off. Also, after it detects you have finished shredding, it does a little 'reverse' to ensure no blockages.
