I have submerged it in a well 6 meters deep, it is very powerful and sends water with pressure to my last faucet 50 meters away. I still need to see its durability over time. It has a paradox in the water outlet, the valve is not aligned with the outlet. It defies the laws of hydraulics. I sent the first pump back and they replaced it as I believed it was defective. And the second one was the same. Eventually, I operated it and it works perfectly fine.

I will come back in a few months with a long-term evaluation.

Update.

It worked for a whole summer as the main water supply source for a house with considerable daily consumption and many on/off cycles, and it didn't fail once. It worked from a well with relatively clean water. It is reliable and very powerful, but be careful with the materials you choose for the network as I had three different pipes and two connectors burst from the pressure. Now I give it 5 stars. The quality-price ratio for this specific type is excellent.
I used a water expansion tank (25 liters) as a storage to reduce the on/off cycles, and it helped a lot. I recommend it to anyone for this exact reason.

In the fourth summer (it only works for 5 months a year), the check valve's rubber broke, but I went to the company's website where they have all the components and I replaced it myself easily. (You need to have some skills in construction.)
