We've been using the Driinkwell Stainless Multi-Pet fountain  for a few weeks now. It was pretty easy to set up. Its tricky keeping the bowl in the base because the pieces slide and it doesn't click on all the way. The motor is very quiet but the falling is constant. It's kind of soothing. I have to turn it off or my big dog won't go near it, she's afraid of the sound. It is easy to take apart and clean. I don't  know if I'd recommend this based on my personal experience of my dogs not liking the water falling. A good product in general.
