I wanted to try out an automatic feeder for my dog since I'm not home all the time to feed him. The PetSafe smart feeder is easy to use. You simply download the PetSafe app, the feeder connects to the wifi, and then you are able to control it from your phone. The only thing I would say about it is it's not that quiet, unfortunately. But I guess it's as quiet as it can be. Overall, as soon as my dog hears the feeder, he runs over and loves watching his food spill out.
