It’s hard to imagine that a drone can be built for just a few dozen yuan. This drone, made of only two sticks, four propellers, motors, a controller, and a battery, has truly reshaped my understanding. Paired with the high-tech-looking remote control, it’s incredibly fun to fly—so much so that you’ll be completely absorbed. It can be flown both indoors and outdoors. Unlike those small planes that crash after just a couple of spins, this one hovers steadily. Fly it however you like, no registration required.
