The Smart Feed Automatic Feeder is so easy to use! It makes feeding so convenient, especially if I am running late or stuck at work. I don't need to worry and I can also take my dog out for a walk as soon as I get home - a big convenience for me! All controlled by an app -yay! Easy to set up and operate. App is very user friendly. All of the parts are easy to remove and wash. It has the option to install batteries in case of a power outage. It has great features such as the slow feed option -great for those dogs who eat too fast. Dispenses small amounts of food at timed intervals. You can set feeder times and amounts. My dog was a bit "what is this!" at first, but I showed her it was a good thing (using treats to encourage her!). Once she realized that it was just a new way to get her food, she was good to go. I am very happy with this Feeder and highly recommend it!
