I don't have it but I have something similar: http://www.thecatconnection.com/page...RINKWELLBIGDOG

It works well for what it is supposed to do. With three large dogs, though, I'm still filling up the resevior at least once a day, usually more. With my three I have to clean it once a week or else it can get really nasty. My Labs are very messy, though. They always play out in the dirt and come in and get it all in the bowl. But, even so, I don't think I'll ever go back to just a regular bowl. This stays clean much longer. Even over the three months I had just Mandy I was changing her water bowl (a regular stainless steel bowl) at least twice a day. Now, with two more dogs, I only have to refill it once or twice day, which isn't much of a hassle. I'd much rather clean this once a week then change out the bowl several times a day.

One thing you have to remember is to not let it run dry or get low. It's really bad for the motor. With this particular fountain it starts spurting out water and it's kind of loud. Otherwise, if you keep the water bowl full, it's VERY quiet. It's the quietest one I've had.
