Just how quiet is the Newport Vessels NK 180PRO

I ran the original NK 180 all last year and just upgraded to the NK 180PRO! There is a huge difference between the 2 motors, as the PRO is noticably quieter, and more powerful. I haven't had a chance to test the longevity and power usage as of yet. Please use my code: JODY791 for a 10% discount from newportvessels.com https://newportvessels.rfrl.co/nrx65
