I do not understand why this product has so far received no reviews. The fountain has a pleasant design, the porcelain pieces are small and handy, not so big and coarse as the Lucky-Kitty fountain, are easy to wash, dishwasher safe and attractive. The pump works quietly, you can hear only the pleasant sound of running water, which stimulates the cats to play with and to drink. The water surface I very large, although the well is small and handy. It offers many possibilities to find a drinking place. The drinking fountain is mounted in a minute and ready for use. The pump is very easy to clean. Special filters need not necessarily to buy, the fountain also works without a filter, I use anyway filtered water from the water filter from which I myself drink water. Therefore no additional running costs and there are no lime deposits. Filtered water is also better for the cats. I got a normal 12V transformer fits into any German outlet. So no adapter necessary. I am completely thrilled and happy. Absolute buy recommendation!
