What Our Customers Are Saying
Its the best thing ever!
I purchased this for my STEM- minded 12 year old. Here is his review:” I have recieved many stem toys before and this is by far the best I have ever recieved. It inspires my creativity by letting me build what ever I want to build with unlimited possibilities.

This was a perfect Christmas gift for my 10 year old son
This was a perfect Christmas gift for my 10 year old son! He has really enjoyed building his own machines and testing them to see if they work. The challenges are great too!

Great learning toy
My nine year old daughter loves to create things and to figure out how things work, so this was perfect for her. She has loved this toy and the challenges that come with it, she has even come up with a few of her own inventions. I also like that this toy has introduced some new vocabulary and produced multiple in-depth discussions about how mechanical things work. Thanks for a great toy!

They thought of everything with this set
My son just turned 6 and he loves this due to the real tools, real wiring and building to truly make something. It is too advanced for his age to do alone but he will grow into it. It does give instructions for 3 different “machinese/robot” builds and requires the user to then take that knowledge to build more. Pieces are high quality. My favorite thing is the way it is all packaged - the manufacturer thought of everything: clear instructions and photos, parts clearly organized with ideal storage containers, batteries, etc. Open the box and begin playing immediately.

excellent STEM toy
This is a very well thought out kit with lots of tinkering possibilities. I have recommended it to other friends with kids to like to problem solve and construct inventions.
