Our beidern daughters (7 and 5) have received this train to Christmas 2009. After construction by Grandpa and dad it took a bit of practice before we could go all something. However, the cars are constantly flew out of the corners or the fly-over. The children lost first Christmas Eve interest. When I had, however, made me at night on various Carrera GO fan pages clever, I could fix the problem quickly. (It depends on the position of the Storm customers.) Since the 25th our two girls playing constantly and with growing enthusiasm so. Our neighbors have also received a GO for Christmas, which our girls have then constructed.
