Flying Mirror Ball Helicopter and UFO-style Flying Object Set I recently purchased this for my 3-year-old, but the recommended age is 5 and up. We tried it twice, but my child wasn't interested, so I'm selling it. It can be charged with a smartphone charger and flies up to about 20 meters while shining like a mirror ball. It also has sensors that react to hands and the ceiling, allowing it to be flown indoors. I think it's a toy that both adults and children can enjoy. It's not widely sold in Japan, so it would be a big hit at a party. It takes a little practice to fly, so why not practice and show it off at a party? It automatically stops if it falls or hits something. Basically, please fly it indoors. A USB charging cord is included.
