Bests & Worsts Reviews from Amazon

Had to return it. It makes a tremendous amount of noise when working, i could hear it loudly clear across the house when i tried it for the first time with water. It sounded almost like something was rattling. I hoped it would go away but it kept going for 20 minutes. I tried it 2 more times just in case, but to no avail. Maybe it was a defective one?
