The quadricopter makes a cheap impression and was delivered contrary to the description without a second battery. The delivery was about 4 weeks to wait, since the products from China will be delivered. After me the dealer to explain in broken German tried that the second battery is stuck in customs, I want to return the Quadrocopter. This should take place at my expense to England! After I returned the item, it has a further 6 weeks lasted until I had my money (!) - The 20 Returns were naturally gone. My money was only refunded after I contacted Amazon.
