The app controls to the Sumo (steer, speed, forward / reverse and jump) and can shoot pictures and videos in parallel. I use the device now, especially on iPad since one on the big screen just looks more. But the driving around in the apartment is great, but the blast is the skip function. The unit jumps about 80 cm high, eg on a chair, but also on stage, thresholds etc. There is also a mode in which the sumo can very quietly, almost inaudibly drive, but you can not then use the camera as this is directed downward. The control requires some practice, but it works quite simple precise to drive.
The processing of the Jumping Sumo seems solid: Although manufactured mainly of plastic, it has kept all stand. The battery lasts about 20 minutes, which is quite sufficient as a rule, but it could be longer.
