Easy to use & cuts a good portion of branches. Doesn’t work well on very small diameter wet twigs. Also, the provided bag handles could be shorter to prevent missing some chips when it’s windy.
CJ603e has done everything I wanted it to do. Bear in mind it is not a "giant industrial shredder", but it turned fifty years of over grown forsythias into an eight foot pile of mulch in one weekend.
It is not a bad unit for the money. For us however it has simply not enough power. I will be forced to buy a gas powered unit soon. This does not handle branches big enough for my home. Probably fine for most homes.

Dear Valued Customer,
Thank you for taking the time to share your experience with the Sun Joe CJ603E Silent Electric Wood Chipper + Shredder. We appreciate your honest feedback and are pleased to hear that you find the unit to be a good value.
The CJ603E is specifically engineered for light to medium-duty shredding and chipping tasks, making it well-suited for small to medium branches typically found around most residential properties. We understand that some users with larger properties or thicker branches may find the power output insufficient for their needs. In such cases, a gas-powered wood chipper, which offers higher horsepower and greater capacity, might be more appropriate to efficiently handle heavier-duty tasks.
At Shop Joe, we strive to provide a range of products designed to meet diverse homeowner needs, balancing performance, convenience, and environmental considerations. If you’d like assistance in selecting a model better suited to your specific requirements or have any questions about maximizing the performance of your current unit, please feel free to contact our customer support team. We are committed to helping you find the best solution for your outdoor projects.
Thank you again for your review and for choosing Shop Joe.
Great little unit. Not meant for large debris or branches. But does a great job with the smaller/ cleanup stuff. I recommend this product for the homeowner with lots of tree, brush, bush cleanup.
The unit performed really well, and this project required 2+ hours at a stretch to get the job done. I chipped mainly Crape Myrtle trimmings and you can see by the photos the chips/mulch came out pretty well. I ran the chunkier bits back through which reduced them further. Before I began I wanted to see how the mechanism functioned, to give me a sense of limitations (photo included for that purpose). Rather than use the small collection bag, I sat the unit in an industrial sand bag so I could keep chipping. I did use ear and eye protection, as well as gloves. Best lengths will be 10-18". One batch I had cut too small. This batch was not destined for this chipper and had difficulty getting into the teeth, this needed coaxing but did get chipped. At the end of the job I opened the unit again and noticed lots of fine material had collected inside the housing. I vacuumed, and used a blower to clean it. I also scrubbed the blade to remove residue build up. Great product, performed better than expected.
I ordered this in Feb 2019 and had to wait for 20 inches of snow to melt off my trash stack. Once started though this device is very user friendly for brush and limbs up to 1.75 inches. Don't do leaves and small twigs as those block up the discharge chute.
