The keystone was built quickly; is meticulously crafted and solid; beautiful that is the Clip-figure can be replaced in the middle other toys and you can attach to the stroller the clip for example. Price unfortunately somewhat expensive. Our little one is excited about the trapezoid, as it is still a bit small and the arms too short, we have extended the game figures with rings (eg JACKO-O) and cut back now if required) or hang out with the rings additionally something to the trapeze. The trapeze we would buy again.
