The decor is very fast of hand - app install, connect and away you go. With multiple iOS and Android devices this involved no problems.
The battery life is approximately 1.5 h given, the maximum wireless range I would appreciate (depending on structural obstacles, indoors or outdoors) to about 30-40 m. The camera technology used could be a bit better. In places, the resolution looks very grainy and the output will be a slight delay. The controller itself is very precise, however possible, even with the integrated position sensor of the respective device. Unfortunately this is not possible - it would be desirable if the vehicle speed influence could be.
Apart from the actual control, it is also possible to store images, outputting audio, and save / call up movements. In addition, a night vision mode (IR-LED) is present, with which the tank can be controlled well even in complete darkness.
