I bought it for olive tree pruning, for semi-professional use (due to the size of the olive tree and occasional use).
Overall, it is good, starts easily, and has enough power for a one-horsepower engine. It is relatively heavy. As someone who is not a professional farmer, I like to take breaks, while this machine doesn't need them. The idle adjustment needs to be done correctly (it has some basic instructions in English, but you mainly find it through trial and error). Its plastic parts seem decent. With the right mixture, the engine doesn't produce smoke or get clogged.
It is advisable to change the blade and chain that come with it, but for starters, there is no problem, they are of average to good quality. The blade needs lubrication at the tip, and the chain is well-oiled and relatively economical in terms of oil consumption. With a thinner chain, it will definitely perform better.
I cannot comment on fuel economy yet.
It has some vibrations, perhaps due to the average blade, and although it is not the lightest, it is balanced in terms of weight.
As for durability, I don't know, but it seems like it will withstand.
Update 11/21/2022: second year this year after almost 170 tree prunings and plenty for the fireplace, and I have the following to say:
1) It starts on the first try with the correct mixture.
2) The chain with the blade it comes with holds up well, but a thinner one will turn it into a diamond.
3) No problem with pruning up to a maximum size of 7-8 cm. When cutting a 30 cm olive tree trunk (size for the fireplace) on the fourth cut, it needed a 15-20 minute break to cool down.
4) Properly balanced in the hand, so it hides its weight.
5) The plastic cover of the air filter would come off when it hit something, but it's fine with a cable tie.
6) With the extension of the harness, it leaves nothing standing.
Final conclusion: If it were half a kilogram lighter and you changed the blade and chain, it would be perfect in my opinion!

For its price and for occasional use every year, it is very honest. It prunes easily, cuts thick pieces if needed. It doesn't bring down trees like the one with a horse. It tires the hand after a while due to the weight of the motor. If you maintain it properly, it shows that it will last a long time in good condition
