The first copy ordered no bubbles wanted to show. The liquid is simply running out again. I sent it back and ordered a new one. This time it was, but you should not expect such a great blow as advertised. Sometimes they just stay behind sticking to the car and did not fly, but my son likes it, and I'm happy that this time überhaubt something comes out behind. Control and steering are properly, but you should not expect a race car. All in all a very appealing product and the price at Amazon is a remote control car also ok, the manufacturer with 50 Euro, the EIA is however totally exaggerated. Since the first did not work I forgive three stars, otherwise it would have been four.
