The boat wuirde delivered quickly. Unfortunately, batteries were not provided in the package. We had to have not in vain ordered Buy also accus and charger. Battery packs with at least 5000mh anything else would have been simply too weak. 8, it was to create not to disappoint our grandchild. This meant a deep grip in the wallet and cost around 105.- Euro again. We had to find out further that the boat for sea was unsuitable because it almost came on the spot because of the tidal current of the sea. In a pool or tranquil lake locomotion would have been certainly possible. To increase the fun factor I pulled the boat. The children had, despite the "lame crutch of boat" their fun. Another criticism of the boat: the entire engine was without seals which might have ruined the engine in a capsize.
