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!

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.

A fun portable building kit
I bought these for my 11-year-old son for Christmas. At first, he didn’t know what to do with them since they didn’t come with instructions. After I went online and showed him the idea booklets, however, he started playing with the pieces and making his own vehicles. I was hesitant about printing the booklets since they are around 70 pages long and in full color, but I may do so in the future to give my son some more ideas (all of his other building block kits came with idea booklets). I think there are a lot of fun things that could be made with these, but it would have been nice to have had color photo ideas included in the tub. I like how the kit is portable and can be taken places easily with the snaps and handle keeping everything in place.

Excellent customer service!
EDIT: Now giving 5stars. The company gave me a full replacement at no cost! They had excellent customer service and I would purchase from them again! I bought this set for my son for Christmas. He already owns a smaller set and it is his absolute favorite toy. The toy it’s self, is pretty great. The only con is the pieces in the shape of balls sometimes break in half. However, my son still uses them to make his own creations so not a total deal breaker. This shipment came already broken. When I opened the package, the pieces were spilled all throughout the box. The plastic box the pieces come in was cracked and the pieces were coming out the side. When I went to lift the box up. The whole lid fell off because it was missing a clip that keeps the lid on. I’m also missing some pieces that I’m assuming were lost because the box was broke. I will keep it because I was planning on getting a bigger box so my son could combine his sets anyway but am disappointed that I can’t neatly wrap this one up.

So much fun ...
.... I actually am thinking of buying a set for myself :-) If I had these when I was a kid, my parents would have had to take me to the ER after staying up all day and all night for a week straight, playing with these things! These were supposed to be a present to beautiful twin boys. I don't have twins. This was a present. I didn't know that you'd have to buy TWO things for the TWINS but I thought this set was enough. They loved it so much that this wasn't enough and the mother had to buy ANOTHER set! It's fantastic! Wonderful product! A zillion of built combinations and lots of fun in the process!

Good product, not as sturdy as I would like though..
I like the general idea of this product however some of the little connector balls arrived broken. I had to glue them back together with some e6000. Otherwise fun and easy to assemble. Use your imagination you can have a good time with your little one.
