Amazing invention, addressed the problem with changing the water twice a day, but we still can't ignore the fact that we have to take care of the person who is drinking the water. It has been operational for close to a month, there were no issues with connecting it with the application (although this is typically not required), and it merely displays the amount of time remaining until the filter needs to be replaced. Additionally, you are able to remotely modify the mode of the water supply or turn the automatic drinker on or off. Filter replacements are readily available for purchase on AliExpress as well as from savvy resellers on eBay. The autodrinker is completely silent, and it does not frighten cats in any way; rather, it only satisfies:)
