Bought this as a gift for my nephew and it isn't very good. From the description I was expecting a secure moneybox with the added novelty of being similar to the robocop robot. In reality the motion sensor part sort of worked, but the disc firing and movement was zero, tried with brand new batteries and still nothing. It would be a lot better if they had given it a mains adapter. The drawer which contains the coins placed in just pulls out, there is no lock and absolutely no security, so for my nephew who is 1 of 4 kids using it to save his pocket money is out of the question, as any of his siblings could access it. All in all as something from the science museum you'd expect more attention to detail and functionality.
