Review: Awesome set, kind of difficult build for kids, but fun once you get it together. - I bought this for the kids and I to build to together and ended up building the whole thing myself because it was kind of a tough build for the kids to follow. That was okay because I personally love building things. First note is it's very big, and for that reason, I like that it stands up tall because it takes up less floor space that way. After we got it together, we turned it on, and the cart moves FAST, way faster than I was expecting. My 6-year-old son was amazed and yelled "Whoa!!! Whoa!!! How are we going to turn this thing off?!?!" haha. Luckily, the cart is really light so it doesn't hurt when you stick a hand in front of it to stop it. You can also easily move the coaster from standing straight up to horizontal without having to change anything, which was a pleasant surprise. It was a hit with the family.
Review: How can you possibly sell this complex toy for only $19.87? - I can't say how long the motor, battery, and propeller will last, but I can say that this is a fantastic toy for the price, if it last a while. I am a retired aerospace structures research and development engineer, with 32 patents. First, KNEX has really figured out the plastic toughness chemistry. I have 30 year old KNEX sets which are still like new. Most plastic toys degrade quickly, but not KNEX. Congratulations to your chemists! I noticed on the box that 98% of the parts are made in the USA, the car comes from China, and the parts sorting is done in the Dominican Republic. My question is: How in the world, how in this universe, can you buy the materials, make the injection molded track and structure parts, make the car in China, ship all the parts to the Dominican Republic, assemble kits (by hand I suppose?), ship them to distributions centers, and then have desertcart ship a kit to my front door, for the incredibly low price of $19.87, and have everyone in that chain make a profit??? Did desertcart make a mistake on the price? Are you somehow subsidized by the US Government? It really boggles my mind! I am mind-boggled! I can see putting a man on the moon for 288 billion dollars, I comprehend that. But I can't see how you can design, build, and ship this toy to me for $19.87. I just don't get it.

### ⭐⭐⭐⭐⭐ Very good STEM toy
*by S***C on December 30, 2017*

My 5-year old son spent days working on this toy and was elated with the action of of the coaster when he finished it. Very good STEM toy. Only (small) complaint is that the track connections (small yellow pieces) don’t hold tight enough while the car is racing around. So the track detaches from the main structure due to the force of the fast moving car. But trouble shooting that is good for the kids too!
