| I have three of the Quiet Ones....and I'm not too impressed with them. I don't think they're that quiet either, although I can't really compare them to other ones, such as a Mag.
What the Quiet Ones definitely aren't good at is maintaining pressure with head loss. If you have to pump the water over much vertical distance, I wouldn't recommend them. Compared to other pumps, they certainly lose quiet a bit with vertical distances.
