One of the best features about the Syma X5C drone is that it's almost indestructible and it's supper fun to fly. It's also much larger than the Hubsan X4 which makes it easier to see while flying and harder to lose or step on, so if you're planning on buying drones for kids, the X5C is a great option.
Another thing you can do with the Syma X5C drone is use it like a mini training drone for the DJI Phantoms. For example, if you want to fly the Phantom 3 manually, but you're too scared to watch it drift all over the place and potentially crash, you can use the X5C to build more confidence by practicing all of the maneuvers that you're not comfortable doing with the Phantom.
