Query: Excellent!!!

This was my 7 yr old son's favorite xmas gift this yr. He is very interested in how things work and why. He has already gotten a good grasp on electrical circuits and their components, and has graduated from using the books for projects to creating his own. The base plate is flimsy, but I can't let one negative piece take away from all the learning and fun my son has had from this kit. It is amazing to watch him sit for hours as he creates, as I am not even invited to help him anymore!
