Good, except not all components included
This is an excellent kit for making lego creations that can be coded into robotics. We love that it can be used with LEGO and LEGO technic for truly original inventions. HOWEVER, while they make it clear that the micro:bits are not included (and we already had a few), they don't make it clear on the packaging or listing that some of the creations require a Joystick bit, which does not come in the box. It's only $30 or so with express delivery to buy one, but by son was very disappointed to spend the morning making the robotic arm, only to find he couldn't control it without the Joystick bit. I don't see why they couldn't include it in the set and add a bit more onto the purchase price if it's actually required for a few of the projects.
