Pros:

• It teaches not only the kids but also kids at heart to do simple robotics. And without us relying on the extensive knowledge in programming this item is definitely a nice one.

• Colors are pretty simple and each color have their own usages and function.

• Lightweight!

• Compatible to some toys like Lego and MakeBlock platform

Cons:

• Can't think of any, this item is really good for me. The price is pretty decent as well because you will have 1 set already for playing/ experimenting.
