Special Announcement: This toy is quite challenging to play, requiring patience. After spinning, you need to constantly adjust the level of the base and the weight of the pads to keep it suspended for a few minutes. Those who think it's easy to master should be cautious. Once sold, items are non-refundable unless there are quality issues. Please note! This is a patented product. Each flying disc is tested before leaving the factory. Do not assume the product quality is defective just because you cannot play it! Please understand!
