“I have had an absolutely wonderful time with this set!! The extra book that's available helps explain further the processes that are happening in the different projects, but even without it, I really have had fun constructing the projects. In fact, I want to upgrade my set to the 750!If you plan on heavy use, you may want to consider the ac adapter, since otherwise you will run through aa batteries.”
“Step by step guides for many varieties of set ups! Once you understand the concept and connections- you can design your own! My kid opened it and played for 2 hours straight Christmas morning”
