Review on Stainless Steel Cat Water Fountain with LED Light, Automatic Circulating Pet Water Fountain - 2.0L/67oz, Ultra-Quiet Pump, Dishwasher Safe - Suitable for Cats and Puppies by Christopher Holker

I like that it's stainless steel which makes it easy to clean. The pump isn't really audible at all, maybe in a perfectly quiet house. When the water is low you can hear it drip down and know when it's time to refill it. I don't know if this is an intended feature but it certainly does work.My only complaint is that the lid doesn't lock down, it only rests on the lip of the bowl. The reason it would be nice to lock the top plate in place is because our cat likes to pull the dish around. This causes the top to fall off the center stem. The bowl with water is too heavy to flip, but the top plate can be lifted.Overall we're very happy with the purchase.
