1. The video included in the buyer's review shows that the machine operates normally without any issues. 2. The buyer provided positive feedback upon receiving the machine. See attached "Receipt Feedback " 3. After receiving the machine, the buyer had their child stuff toys. The video shows the machine operates normally without any issues. See attached "Customer Sent Video of Normal Machine Operation." 4. After using the machine for a period of time, the buyer without any reliable evidence, demanded a full refund or a free gift of a different model. We do not understand this.

Alibaba officially evaluated our dispute and determined that we were not responsible. 6. We‘re deeply puzzled and surprised by the buyer's unwarranted attempt to get sth for free.
