We actually have 3 Petmate flow waterers in the house. All the cats love them and I love them because I don't have to be refilling water bowls all over the house twice a day. We add water to them about every other day and at least once a week dump and clean and refill them. But it is sooo much easier and the cats love drinking out of them. Katie also doesn't splash the water about the house as much.
