This is a very high quality pet fountain.  My dog loves it!  Now I don't have to worry about her not drinking enough water because she drinks all the time now.  I really like that it keeps the water fresh all day long.  I also love that when taking apart and cleaning you can put it in the dishwasher on the top shelf.  I am impressed that it is also very quite.  You don't even know it's on. I am very impressed with this fountain and highly recommend it.
