Before I bought my second TrainPod needed ish already another which funkionierte wonderful. The rubber was flexible, the air remained to train a pleasure it. I then bought another, but which I had retourieren. The rubber was deformed even after inflation remained a dent. He was so hard that a jump so that was impossible. The next, which I was sent to then, was the same year 2011, and the rubber is again rock hard. Useless! Not recommended, makes zero fun. 2012 Model: Train Pod-Cyan (RAP 40180CY), however, is excellent.
