PETLIBRO products come with detailed instructions and are easy to set up and use. The Smart Feeder, for example, requires users to download the PETLIBRO app, create an account, and connect the feeder to Wi-Fi. Once set up, users can schedule feedings, monitor their pets' eating habits, and receive notifications about low food levels. PETLIBRO also offers customer support to help users with any questions or issues that may arise.
