I just came home tonight and I noticed only 2 Tablespoons of food in the Dog's tray.Normally the machine dispenses for 2 minutes, or about 2 cups of dog food. The poor dog would starve if I hadn't noticed this.I will attempt to contact the manufacturer on Monday. The warranty is only for 90 days and this should have been a clue to me prior to purchasing a $140 piece of plastic..
