5.0 out of 5 stars A huge variety of projects and fun
Reviewed in the United States on March 11, 2018

This is the best surprise gift "Santa" has ever brought home. My 8 year old is obsessed with them. He particularly loves building the radio projects, and will sometimes put it together just when he wants to listen to music. One complaint is that two of the blocks have had one of the little conducting pegs fall out of the bottom, so they don't work anymore. Still a great buy for any kids who love legos and/or science!

I saw these at an Educational Technology Conference (IDEACon) and bought them for my 5-y-o son. He and his cousin loved them so much that I bought another one to send to his cousin, who is 6. He LOVED it, and it was so cool to see all of the things they could do with these! There are additional kinds as well that I will try in the future. Great, fun way to incorporate STEM and creativity, even at a young age!

This is a fun toy. My son had a blast with the different configurations, but it was very difficult to get the radio to actually work. After about 45 minutes of pressing and squeezing we finally got all the connections to work.

5.0 out of 5 stars Fit together well, easy to follow directions
Reviewed in the United States on February 2, 2022
Verified Purchase
I bought this for "the grandkids" (no, really) and was very happy when we put the first few projects together. It was easy to assemble and worked as advertised. The various components were color coded which made assembly quick and accurate. The only suggestion I have is some components (blue cubes) carry current and some are only structural and could be easily confused with each other allowing for the circuit to not be completed. My granddaughter enjoyed it but I think I was more pleased than she that it worked as well as it did.

5.0 out of 5 stars Bought this for my niece for Christmas
Reviewed in the United States on February 3, 2019
Verified Purchase
I bought this for my niece for Christmas and it was her favorite gift by far. She immediately wanted to stop opening presents and start building with this kit. We spent a couple of hours that night building at least half the project in the included book. Shes 7 and I'm 30 and we were both having a great time. The radio was pretty neat. My brother tells me that is on of her favorite toys now and she want's to play with it all the time. Overall the kit is well thought out the instructions are pretty good. The biggest issue that I had with the kit was that some of the pieces (notably the logic boards) have an orientation to them and the markings on them that show this are sometimes difficult even for me to discern. Secondly although the instructions are great with lots of pictures they need a better way of illustrating the layers, I could figure it out but my niece was having a hard time with it... Overall even with those minor complaints this is an excellent product, I will be buying more of these in the future. Its so important to teach the sciences to young minds.
