Excellent for a youngster with engineering ambitions

I bought this for Christmas to my nephew (he's 7) and he loved it: it was challenging but not complicated and managed to do it all by himself. Nice gift :)

Unfortunately all the information on the box and the build instructions were not in English. No problem with the return though.

A present for a grandson.

My son loved it, it’s easy to built, instructions are very clear and pieces are good quality

muy bonito y didactico, a mi sobrino le encanto, lo unico es que las instrucciones vienen en ingles y el aun es muy pequeño, pero todo lo demas bien

I was hesitant at first because there weren't many reviews for or against, but I purchased the ENGINO-Stem Mechanics Gears and Worms set for our 9 year old grandson and he loved it. He is into anything with gears and STEM related that is creative, sturdy, makes more than one project within a box, and actually works; this was a hit! It also arrived very quickly, in great condition, and will be enjoyed for a very long time. I will most likely be buying some of the other sets available from ENGINO-Stem so that he can learn about other mechanics and build even more.

Llegó a tiempo, en buen estado. Es un producto didáctico al 100%. El material de los bloques es bueno y el de los ejes no tanto porque se doblan un poco si se manipulan mucho. Sin embargo, son más las ventajas del producto.

Fabulous kid experience with clear dirctions on how to build the several illustrated structures. Great physicas esson embedded!!
