Once we had figured out that the amount of water in it is critical it worked very well. UNFORTUNATELY none of my cats is interested in it. In fact, they are a bit worried by it because it makes a noise.
Nice looks, works perfect, my cat loves the flowing water, makes no noise. Delivery took a while, but it is worth it.
We have three cats and our cats are loving this fountain. They drink more water than they used to. It stays cleaner than our old fountain.
