I bought it for the village, where I started cutting branches from cornel, cherry plum, and walnut trees. I assembled it and it seems to be a sturdy build. I still need to figure out how the blade is adjusted so it produces as fine a cut as possible and not coarse pieces, and to get a gasoline canister, while the one already included in the package I will use for oil.
In essence, that is the only downside I found: the 2 oil caps, which are low on the base of the engine, one in front for filling and one at the back with a dipstick integrated into the cap for checking the level. As for the oil, the store where I bought it recommends 15W50, while the English instructions recommend 10W30, depending on the minimum and maximum ambient temperature. That’s all for now, and if you buy it, bring a second person with you for help.
Thin wood sheet packaging and yet it weighs 60 kilos! It includes earplugs, a mask, a pair of gloves, instructions, assembly tools, and a 1L gasoline canister.
I reserve the right to come back with some tangible results!

I bought it recently for my garden but also for the olives. Many told me that to get the job done you need to spend 1500 euros on a shredder. I couldn't spend that much. So I got this one. Although it is small, it is very good, powerful, and quite fast. Its disadvantage is that the base of the funnel where the blades are is very narrow, resulting in branches with large tufts not passing through easily. If the base and the blades were 5 centimeters wider, it would be perfect. For dry branches, it is not very effective.

Very good machine for my needs.
It is direct drive (it does not have a drive belt like the larger models), but it is quite powerful.

I changed the first oil after 5 hours, as Unimac recommends (the manufacturer says after the first 20 hours).
The oil should be API SF and above (e.g. SL, SP) and the more often you change it, the fewer deposits and the better the engine's longevity.

Do not expect it to handle small branches and leaves and this is perfectly logical.

I will contact Unimac to purchase blades for the future and after further use I will return with more details.

I tried it a few days ago by shredding 130 orange trees, 13 years old, that I cut from the root. The maximum thickness I shredded was about 40mm; I kept the trunk and the thick branches for the fireplace. It worked smoothly, even though the orange tree has hard wood, five days for 4-5 hours daily with breaks to let the machine cool down. It shreds the wood satisfactorily, and although it doesn’t have bearings on the blades, it pulled the long branches by itself. I was very satisfied. Among the many positives is its light weight, 45kg, which makes it easy to carry and pull in the field.
