Fun product/Great customer service
I knew my 2.5 year old son would love these trucks that you could take apart and put back together. It has everything he loves- trucks and tools! I kid you not, within the first hour of giving him the toy, he had disassembled everything AND unfortunately, lost 3 of the screws. Without them, we couldn't put 2 of the 3 trucks back together. I was so upset! I emailed the company and they got back to me right away. They are sending 12 replacement screws! That is so awesome because, knowing my son, we'll probably need them! He'll be so happy to play with all 3 trucks! I also like the buttons on the trucks that have music and truck sounds. I definitely recommend this toy! And good customer service is always comforting. It makes you want to buy more products from that company, knowing they will take care of you if something goes wrong.

Great Learning Activity
I bought the IQ BUILDER STEM Learning Toy for my 6-year-old grandson, and it’s been a huge hit! He absolutely loves the challenge of building and constructing with it. The pieces are easy for him to manipulate, yet complex enough to keep him engaged as he builds different structures. It’s not only fun but also a great way for him to learn about engineering and problem-solving. The quality is excellent, and the instructions are simple to follow, making it enjoyable for him to complete each project. I love seeing him so focused and excited while learning. Highly recommend this toy for any child who loves building and creativity!

A great toy!
Our grandson loves this IQ Builder Toy! I think it’s great too. My only concern is that the 8 wheels come with 8 tiny axels. I am sure some will be misplaced, and think a few extras are in order. Would you consider sending us some? Thank you

A favorite toy
We bought this as a second set. Now there are enough pieces to make even a large “castle” or to build multiple vehicles. The sticks can go into the balls at so many different angles that the possibilities of building different shapes are almost unlimited Bought the first set for 3rd birthday and the second set for Christmas. Note that the balls can split in half - not while playing, but possibly from being thrown or stepped on. It has happened to only a few out of two big sets.
