“We bought this for our 10 year old son for Christmas. His teacher actually had a set from one if his grown kids that he lets his students use. So, this was at the top of our son’s wish list. It has provided hours of fun for him. Instructions are detailed and easy to follow if you can build a Lego. The photo on the front of the instruction book is actually a working radio that you can tune to your local station. All the the sets also interconnect. We also purchased the light up snap circuit set. This is a classic toy…up there with magnet tiles and legos.”
“Very easy to use the pieces. Projects from very simple to complex. Can do by the pictures or actually read it. It does explain the science and engineering behind it if you want to read it. Read several who said no or didn't know but yes it is there. Have gotten 4 kits now. Started out simply when my granddaughter was 4, now she is nine and I got a more complicated one for Christmas. We have already spent hours on it. Very satisfying I taught science from 6th to 13th grade for 34 years. Would have loved to have had these for my students. Highly recommended without hesitation. Also, if a part broke within warranty had swift replacement. Got hair tangled in the motor. And all pieces from all kits work together!!”
