??Easy to Play?With Altitude Hold, Headless Mode and One Key Taking-off / Landing/Return, you could fly it without worrying about the direction and control it easily. ??Longer Flight Time?Compared to other similar types of drones, the H823H has three 3.7V 300mAh batteries, which means longer flight times up to 21 minutes. ??Having Fun?360° flip and three different adjustable levels of flight speed give you a different flight experience. Let you advance from novice to master. ??Durable & Full Protection?The complete-cover outer case made by nontoxic soft plastic material perfectly avoids not only body injury but also machine collision damage caused by improper operation. ??Cool Mini Design?This drone is perfect for flying indoors. It fits in your palm. I wouldn't recommend flying outdoors unless you are in a large area as slight wind can blow it different directions, which is expected from a mini drone.
