So now that I already paid for the FX-STP pump and found it to be extremely noisy, I came here to find several others have problems with this pump as well. According to melev this thing was supposed to be nearly silent. Mine? Nope. Stepper motor noise and tons of frequency whine at all speeds. So has anyone been able to get this corrected anywhere? Coralvue? Kamoer? With this much vibration noise and frequency whine I doubt this thing is going to last a month.
