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.

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.

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.

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