Review on Engage Your Child'S Curiosity With The 5 In 1 STEM Kit - The Perfect Educational Building Toy For 8-12 Year Old Boys And Girls by Brian Barnes

I was very impressed by the fact that they gave 5 separate motors and battery units , which allow you to build and use all 5 vehicles independently. Usually kits like these have you reuse the electric parts, but this is great -- no disassembling and taking out vital parts of the old vehicle required! you can run all 5 at once!great for kids 8 and up. Instructions are easy enough to follow but I took one star out because of come confusion caused by different colored parts than stated in the manual (but my genius boy, smarter than me, figured it all out while I was left scratching my head.)
