Review: Great hands-on toy, brings out creative genius! - 109 Piece Educational Engineering Building Set for 4, 5, 6, 7+ Year Old Boys & Girls. Fun Learning Construction Blocks & Gears Kit makes it the Best STEM Toy Gift for Kids Ages 4yr - 8 yr. He's sleeping with it, he loves it so much! Great hands-on toy, brings out creative genius! We did a STEAM themed Christmas for our 4-year-old this year (wanting to get away from all the electronic gadgets) This toy was an instant favorite. He started building with it the minute he got the wrapping paper off of it. It is his go-to toy every morning as he heads into the playroom. He loves creating "houses and castles" with the set that include numerous linked spinning gears. Because of the size of the pieces, it is easy for him to manipulate on his own. Every day he creates several different structures. I can see the engineering skills growing in complexity each day - he has even built structures similar to the idea sheet pictures 100% on his own! The favorite heads up to bed with him every night. He incorporates it into the nighttime story he makes up for me each night. I am so happy we bought this and highly recommend it to others!
Review: Well made and great creative play! - I bought 2 of these as Christmas gifts for my 5 year old twin grandsons, but they stayed with us the week before Christmas and the weather kept us indoors pretty much the whole time. I needed some indoor creative activity and brought these out to play. So glad I did! The boys played with the building sets for literally hours. They particularly loved the gears and built all kinds of "machines" and "vehicles" with the components of the set. I highly recommend this set for the 4-7 year age child. Very well made, sturdy, colorful and provides unlimited creative play. If more than one child is playing I definitely suggest getting 2 sets so there are plenty of wheels and gears to share!

### ⭐⭐⭐⭐ Great Contraction Toy - a bit hard for a young toddler
*by J***E on August 19, 2016*

Wonderful construction toy. I bought this for my daughter after buying the Construction Engineering Blocks from the same company. My daughter loved the Engineering Blocks, and she likes these but they are harder to build, she's almost 3, but I have to help her build them, some of the pieces are hard to get in, while other pieces seem loose and will occasionally fall off (the wheels). I'd give this toy 5 stars if it came with a "tool" to help build everything or connect the pieces, so that she could do more of it on her own, rather than telling me what to build and just sitting next time me watching.
