I have been wanting to buy a water bowl that constantly supplies fresh water for my pets.  This is great.  It has a carbon filter that cleans the water and the filter is easy to change.  Also, the fountain can be washed in the dishwasher. Everything comes apart and it's easy to put back together.  Makes it super easy for cleaning. The fountain is quiet and there is no splashing. My dogs and cats enjoy drinking from this, and they have a constant flow of water.  It hold about 60 oz of water.
