I for my part also buy the big box on wheels containing the Hello Kitty school. My fear was that it is not compatible with another brand. But if: you can mix everything to enlarge the collection for less! All basic parts are identical. Then there are elements that are unique to Hello Kitty. I am very satisfied with my purchase. It should be noted that even when the price difference perhaps is that the pieces fit together a little less easily than those of the competitor and assemblies to achieve the world of photography are a little more complex.
