This automatic feeder is amazing! The feeder holds up to 24 cups of food and has a sensor to let you know when it needs to be refilled.  Some of the other great features include the ability to use semi-moist food, the bowls are stainless steel, and an optional battery back-up.  
However, the best feature is the Smart Feed App that offers you the ability to schedule your animals meal(s) and quantity.  Its has come in handy so many times when we were not home at dinnertime to feed our dachshund.  I know she appreciated it!
