I bought the machine about 1 month ago. Of course, the time is minimal but it works very well. The comparative advantage of this particular model is that it has a built-in pressure tank, which means that the water pump does not start immediately when we open the faucet, although the water runs immediately, but after a short time. This way, the pump is protected from continuous stress from short-term water use or small leaks. I consider this to be a significant advantage.
