my mom has tried other fountains in the past and her cat wouldn't go near them because they were too loud. She loves this fountain though. We set it up and in less than 10 minutes she was happily drinking out of it. We love that its so quiet and you can adjust the water flow. Putting it together took a little bit of time to figure out. Super easy to fill although I wish it had a fill to line and a low level line or better instructions on how much to fill it and  when to refill it.  Otherwise great product love it !!
