Second year of use... I water 2 acres with a drip (around 500) and it manages satisfactorily. I set it to give me 2.5 bar and it fills it up just fine... I left the intake as it is. (previously, with a two-stroke campeon, I had 2x2.5 for 15 years and it drew almost double the amount of water!) At full throttle, it heats up at some point and gets slightly confused... but one click before full throttle, it doesn't have any major issues... On the downside, the small reservoir and the makeshift cables... With proper careful use and maintenance, it works perfectly fine!!

Conclusive little machine for watering and other small tasks.
Advantages:
Naturally, the low cost.
The lively and fuel-efficient engine.
It starts easily and brings water quickly.
It is very easy to transport as it is lightweight and has the appropriate handles.
Disadvantages:
If used with a fire hose type handle, the flow decreases as it does not generate high pressure.
The metal covers are very thin and in general, the whole machine is a bit fragile and needs to be protected from impacts.
In my machine, the input-output fittings were plastic, but I haven't changed them yet.
