1.0 out of 5 stars
Nice idea, but poor quality materials, 27 Nov. 2011

A promising idea, but several component parts are small & fiddly to put together. One key component fell apart during the first stage (making the gear box) and would presumably need to be soldered together again. I can't imagine many children putting these together. The product is considerably more fragile than the images seem to convey.
