This fountain has a big reservoir and a soothing waterfall sound to it. It works with Alexa and Google if you want to use features like turning it off and on, and the app allows you to schedule times when it turns on and off. I’m not exactly sure why you would want to turn it on and off, but I’m sure there’s a use for it. I didn’t find the app features to be something I would use. I don’t really need to be notified when it’s getting low, but I can see that being handy for some people. I like that the water is constantly moving and filtered so I know my pets are getting fresh water. It has a nice aesthetic, too—very modern looking. For our medium-sized dog and with evaporation, I probably have to refill it once a week and that is good. Overall I’m happy with the fountain and would recommend it.
