I bought the boat for my three year old daughter. Well, probably a little too young. The boat, however, is really great, looks nice and has a few nice touches. The few component assemblies that existed were grown quickly. Maybe you should get stuck the battery pack with Styrofoam blocks. By which I am not at all clear came, was to ensure that the boat only starts when it is in the water. Here a line has been cut and each soldered to a pipe shaft. That was me too uncertain and I have both solder joints connected by wire again (soldered). One should be careful, of course, now that the motors do not start when wearing the boot. Whether this change is really necessary, but I can not judge Also, I would find it nice if it would be a 2.4 GHz radio control. But really a nice toy and recommended for the price.
