My extremely smart and talented ADHD kiddo loves these STEM KITS! They are great quality and perfect challenge and fun for him. There were no missing parts. The sale price was a great deal and the age range is perfect on these.

My nephew is six years old and really loved putting these toys together! Highly recommend this gift for any child that would like to learn about laws of motion and early engineering! Some of the projects did require help from the parent. Overall, a great interactive activity. No missing parts. Accurate web description.

This kit is AMAZING!!! My daughter and I put together 3 out of 5 contraptions so far. They were obviously designed with great care, some spare parts, precision, all three work really well. Great value for money too. Great demonstration of engineering/science principles. It was super interesting even for me as an adult. Got 5 more kits to give out as gifts.

These are very neat. My 7 year old put them together mostly unaided but with some parental guidance and assistance. They had motors and movable working parts which worked well. The only downside is there are lots of small wooden parts which were at times fragile to push out of the wooden sheets. They are also easy to mix up. So just be cautious when organizing the pieces.

Our children really enjoyed putting these together and have gone back to play with them many times. However, the build was more difficult than it should have been because the instructions weren't the best grammar or very clear on certain steps. Even with a parent, there was a little trial and error as to what was being communicated. That being said, I would definitely recommend these activities for upper elementary aged kids.

Made of cheap wood, so it was partly broken while I detached the parts.The final products were not very sturdy...It was a bit hard for my 6yo girl, so I had to do most parts.But my daughter could take some simple and easy parts.

Love it !

thanks
