I've had one for about a year and I love it. It keeps the water fresh and the kitties seem to drink out of it more than they did when I just had regular water dishes.

Actually I just went to look at it and I have a different kind of fountain, it's the Fresh Flow. It's a little different as the water runs down a ramp instead of it being "faucet like". I think it's quiter than the drinkwell.
