Fun to build! Kept my 9 year old busy and entertained for a while. The materials were of quality!

These kits have led to wonderful times with grandkids, 7 yo old is fascinated. Beware, screws and wires are TINY and adult has do the small parts. Not a toy for long life, but immediate fun and the science exposure are great.

Terrific set teaching fun concepts. For my young kids these lasted about a day.

Kids (age 8 and 10) loved these though some of the connections between the parts and the tray seemed big and caused splintering when separated. Fixed with sandpaper the rest of it was hours of fun for the kids. Gets them thinking about how things work and go together which is great in the current overly digital age.

I put one together with my 7 year old grandson handing me the next part. Very entertaining. I had to break out my glasses, the screws are tiny. We had fun. He took the other 3 dinosaurs home with him for his parents to help assemble.

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.

Easy instructions to follow. They young lady loved putting them together and seeing it work once she was done.

Two of these were missing instructions cant figure out how to contact to see if we can get digital instructions sent the solar system and tension plate have no instructions. If able to respond I am willing to change this review if resolved
