Endless Building Fun That Sneaks in STEM Learning! 🧠
This building set is an absolute favorite in our house. With 100 colorful pieces, kids can build endlessly while learning how gears work together—turn one, and they all move! It’s fantastic for developing fine motor skills, problem-solving, and early STEM thinking, all through hands-on play. The pieces are sturdy, easy to connect, and sized well for young hands. It keeps kids focused and engaged for long stretches, which is a huge win for parents. Tip: Start with simple builds and encourage kids to turn one gear at a time so they can see how motion transfers—it really helps the concept click. I highly recommend this STEM toy set & I hope this review is helpful 👍🏻

Great Toy, Just wish there was more.
My son and I had been over at a friend's house and they had a set of these. The two boys had set to making all sorts of things rather quickly and I was amazed. The set was really cool and seemed to bring out a lot of their creativity and imagination. I thought it was neat especially the way that it helped them think and decide how to build things and what they could do to get all the gears to work together. Together we all built cars and neat things that had moving parts. So when we got home I ordered a set for my son because of how much fun we had with it. When it came we did the same thing. We opened the box and began going through all the things that we could make. But, I found one problem. I wish there was more! The set I feel falls a little short. It only has one crank handle. There should be more. Because if we both make two things one person has to crank things by hand while the other gets the handle. I don't mind this for myself, I'll use my hand. But, the thing is.. it limits what you can do. I also wish there were more connector pieces. The pieces that go between the gears. Because it would be nice to build bigger things. You almost need to order a couple sets at once. However, with the one set that we have, we have created some fun stuff. Getting around the lack of extra handles and lack of connector pieces. We have had a great deal of fun with these. I love watching my son build cars and trucks with wheels and other moving parts. He has a lot of fun with them and I think they are great busy toys especially for boys with those building minds. My son is always building things, and this was perfect for him.

Super Bausteine. Funktionieren ausgezeichnet. Mein Enkel 4 Jahre kann davon nicht genug kriegen. Gesten hat er einWaschanlage gebaut. Der Kreativität sind keine Grenzen gesetzt. Die Bausteine mit den Noppen will er nicht mehr anschauen.
