I have honestly been very impressed by the power of this little machine. I had a boxelder maple come down during a storm. I thought it would have trouble with the hardwood. It has not. If it could fit down the chute, it would fet monched. Only real complaint i have Is that wheeling it around is awkward. I have ended up giving myself many deep bruises on my knees and calves when the edge of the chute rams into them while i moved it around, and I'm 5'8". Over all, this was a great value for my money

It took a bit to figure out how to assemble, but once I determined I had all the fasteners, I was able to assemble it quickly. I was a bit perplexed that there seemed to be 2 oil filler caps, but once I realized only one had a filler scale, I was able to quickly fill with oil to the proper amount (still not sure why 2 caps?). It started on the 1st pull - seems to be a great running engine. I started shredding old, dry, in some case a bit rotted tee branch material of various sizes

Arrived sooner than expected and very well packaged. Assembly was straight forward with decent instructions. After adding oil and gas, it started on the first pull. The engine is powerful and controls are well placed. I especially like the variable speed control. This unit is primarily a chipper so it does a poor job of shredding but will eat up leaves and twigs if feed slowly. Three inch green Douglas fir limbs bogged it down and stopped. Two inches is no problem so anything bigger I just split before feeding. I was using a standard garbage can to collect the mulch output when I suddenly realized that the exhaust muffler was to close to the garbage can causing it to melt. I now use a five gallon bucket since it sits below the muffler output.
It appears that it will be a major task to replace the blades as the entire unit needs to be disassembled. Additionally, there was no listing of any part numbers for either the engine or the chipper itself which will be problematic in the future. Overall, I am very happy with my purchase and would recommend this chipper at a very reasonable price.
UPDATE: I have used the chipper for about ten hours and it works pretty well but the blades became dull rather quickly. I was chipping mostly green Douglas fir limbs and some dry oak branches. I was surprised how fast they became dull. I purchased a replacement set and replaced the dull blades. The process is quite difficult. The entire chipper must be disassembled to get to the blades and its difficult to get the bolts off of the original blades. Other chippers I have had were much easier to access and took a lot less effort. After replacing the blades it works great again. Overall, I like the unit a lot but blade replacement is a real pain. UPDATE: I have now used this chipper for four months. The engine is great and starts right up. The #1 problem with this chipper is the blades. They become dull VERY fast. After about an hour of use (chipping oak limbs) the blades effectiveness drops to about 20% of normal. As a result, the blades need to be replaced. In order to replace the blades, the unit needs to be completely disassembled, new blades installed and then reassembled. The process takes between one and two hours. I spend more time replacing the blades than I do actually chipping. It's a shame because with new blades this unit works great.

Pictures show hand full of well chopped up sticks...
My hand full was mostly 3 to 6 inch twigs....
It may be because it was not a dried branch but still I was not impressed....
With most any tool ...it takes practice so I will re submit a review if things change for the better...

As I considered all things, including the price, I gave this product a 4 overall. I could see giving it a 3 because there was a bit of learning curve and it is easy to clog if you aren't very careful. But there is an old saying: "You get what you pay for." The next price point is twice the price then 3 or 4 times as you move up the scale. So, I've decided to keep the product, feed it slowly and watch the chute carefully for signs of clogging. With the wood I'm working with now, 3" diameter will not feed through the tool. I suspect I'll find types of wood where 3" will feed. What I'm doing now is wet and clogs if I feed it. The chute needs to be opened all the way. This helps with clogging.

The tool was easy to assemble. All the parts where included and the instructions were easy to follow.
