Learning Resources Gears! Gears! Gears! Treadmobiles Building Set, STEM Toys, Develops Early Engineering Skills, 108 Pieces, Ages 5+

Another great builder project with treads! Nephew enjoys this one. He really likes STEM toys.

I followed a reviewers advise and bought a basic set of gears to accompany these. The kids loved this toy. All three grand kids were able to play together with these. Even the two year old was able to figure out how to build with these. They were busy for hours.

Easy for adults to help little ones. And easy for older kids. It brings out their creativity.

I think this pack is meant as an expansion to the original set of just gears, but you can totally play with it just by itself. Actually, if you were going to get just 1 single pack, I might encourage this one because it has much more variety of things to build with, even if there are fewer key pieces overall. I got this with a more basic set of just gears, so we have our bases covered. I have to admit that when I saw the toy, I was thinking to myself, "well that doesn't look very exciting" but the kids seem to disagree--they have been excitedly playing with it for a couple of days now. I'm still not convinced it's going to have a ton of staying power, but they have let their imaginations take this concept and run with it. I've been pleasantly surprised to see just how many gears you can attach together and they all operate very smoothly. Eventually if you get enough of them and have them going up columns and around corners and things they do start to get a bit harder to mesh all up and you do get some seizing from time to time, but it has exceeded my expectations by far. And the cousins were thrilled by it when then came over, too. A great way to keep kids off screens and entertained. Time will tell how long it holds their interest...

Lots of pieces but, a well made toy for learning and teaching.

My five year old loves this toy. Easy to learn and many things to build.

Un buen jueguete

The other more open-ended playsets are a better example of this concept. As a build as designed kit there are issues: The yellow and blue gears have different versions that look almost identical which causes confusion. It would be better to make these different colors. The tracks break easily. Some of the gears do not engage well on the primary design pictured on the cover. More gears / parts should be included in the kit for this price.
