Hello all. I am confused. According to the description, it is a quiet vibration pump, and according to some videos, it is barely audible. But I tested the machine briefly and it is quite loud. You can hear a hum through the entire housing. The machine is stable and straight on the kitchen counter. It also makes a disturbing noise when water is drawn in. A very high-pitched whistling or squeaking noise. Has anyone had similar experiences? Unfortunately, I don't seem to have much luck with the machine :( I would be happy to hear from you.
