The set was presented to two noys of 6 and 8 years. First we unwrapped all the pieces and then started to build the circuit. Putting the parts together was easy per the schematics , diagrams and written instructions. In quick order my both together built thr circuits and was very happy with the results. They've learned much about electronic circuits and I feel that my present was a hit. I would highly recommend buying this product.

Super fun toy circuit action experiment. It takes long time but not to leave the kids bored - my daughter had a blast building this with her father!

What an excellent way to introduce your child to circuitry and electricity! We were thrilled to create and see how the whole thing worked! Loved building and creating in a science setting.
