Review on Building Baseplate Interlocking Construction Educational by Justin Spoja

Based on the description and photos it looked great when I got it for my 4 year old grandson. The first thing I saw was how small the parts were, I don't think they were even 3/8. Inch, then after we got into it I realized that there were no connections, no connections between male and female, so it really messed with the construction, and there were also a lot of parts that were completely useless to the you couldn't use anything. Actually very frustrating, I'm a contractor, I know mechanics, thought this would be a good teaching aid for my grandson, NO! who designed it?
