This water fountain has some really useful features.  I love that the app lets me know when my cat's water needs refilled or the filter needs changed.  The UV sanitizer helps keep the water clean.  I like that I don't always need to have the fountain wirelessly connected to my WiFi.  The fountain will run without being on WiFi but WiFi is required to use the special features.  My only suggestion to improve this fountain is to offer a stainless steel version.  I try to avoid plastic dishes for my cat since plastic tends harbor more bacteria than stainless steel or ceramic.  A ceramic or stainless steel fountain with added features would be purrrfect, especially for cats like mine that get cat acne on the chin.
