The Smart Feed Automatic Feeder has great features and is easy to use. All of the parts are easy to remove and wash, including the conveyor. It comes with the option to install batteries in case of a power outage. The app was simple to install and navigate. You can set feeder times and amounts easily, as well as dispense food any time. The slow feed option works well for dogs that gobble their food, dispensing small amounts at timed intervals. We tested all of the options and they work as expected. My dog was a bit uncertain at first, but with a treat in the bowl she was willing to approach it. Once she realized it was her food and her new bowl she was all set. This is a great option for pet parents that might get stuck at work and don't want to delay dinner. This would also work well to feed the pet before a pet sitter arrived so that the dog would be ready to be walked. Highly recommend!
