I bought this, but it seems to have been too difficult for my pet, and it didn't work out. I only used two buttons once. For those who want to have conversations with buttons. It seems like it could be used as a party favor button, not just for pets, so if you can use it, please do. The recording button can be used not only for pet training but also as an interactive toy for parents and children, or as a language education toy for children. You can record your favorite words, music, and messages, and use it in various ways. Packaging method: Bubble wrap #CommunicationGoods #PetConversationButtons #TalkingPet #WithRecordingFunction
