4S30 10-Sheet Micro-Cut Commercial Shredder

Does an excellent job shredding and is very quiet as noted in specs. Still putting it through its paces to see how well it handles everything. It does shred slower than my previous Fellowes shredder.

I've only owned my new Bonsaii 4S30 for a month or so, but it quickly surpassed any previous home shredders I've owned. Sleek design, easy use controls, smooth flow, large bin, separate CD collection bin, delivered when promised. Best of's so quiet! My husband no longer has to crank up the volume on the TV when the shredder is running! This product was worth every penny, thank you.

Love this unit

Being someone who is paranoid with PII and HIPAA, I tend to shred and then burn everything that has no reason to be filed. This unit has proven to be amazing to handle shredding jobs at homr with acceptable cut sizes. I would recommend this to anyone looking to shred material at home.

Auto shut off broken

I like the confetti shreds and it is very quiet. I have been using this machine for a little over a year. The auto shut off no longer works. So if you have a delay in shredding for a more than a few seconds, you must manually shut the unit off. This is annoying.

Quiet and Quality Micro P-5 Shredder

I absolutely love this micro shredder. I researched many top quality shredders like Fellowes and the Amazon brands but this by far is the best shredder for the money and for performance. I have used a fellowes before and it has to take a break after 20 mins, this Bonsai shredder can go 60 full minutes before you need to give it a break. It has a 30 mL bucket for shred collection and it has a separate small bucket attachment for CD and credit card collection (see photo, it attaches in the back). I got tired of shredding before the machine did (smile). I purchased the Bonsai oil and oiled shred maintenance sheets as recommended for this shredder. You can use any shred veggie oil but I would recommend buying the products oil to avoid voiding your warranty. The sheets work well and the oil has a spout that reaches down to the blade to keep them running smoothly. So far, no complaints. Great P-5 security level shredder. ( "P" level refers to the level of paper shred the machine will do. The higher the number the smaller the pieces are shredded) See photos of shredding. I highly recommend. Best investment yet. Oh yea, the container is made well and of good quality too. I have read complaints about other shred containers being thin and have cracked after multiple use, this container is on small rollers and it's pretty thick, so I am hopeful it will last.

4S30 is the best shredder I have owned.

This shredder works great and really does a great job micro cutting. The unit ran without overheating for over two hours on a hot summer day (no AC).

Seems to work very well

Wheels are ridiculous. They need to change the wheels for larger wheels, more durable and strong. They do not even rotate and they are tiny for this model and this price. Machine is working very well. Strong motor and works as described. I just wish the wheels were better. It is difficult to move around. But the best shredder I have found for the price. Highly recommended except for the tiny wheels!
