“Compramos 1 para probar y fue un éxito, así que nos decidimos por un 2do juguete; lo han disfrutado mucho armándolo y hasta encontrándole otros formas.”
“My 9-year-old grandson really loves this. He was able to assemble on his own and I love that he has options to make other things and he is not done with the puzzle after he makes one thing. He gets to take it apart and start all over and make something else. Great toy!”
“I purchased this for my 11 year old grandson. He is sitting next to me and I will quote what he has to say!!I like that there are multiple builds, you can use them for random things, using them with Lego's (that adds to the fun of this product.) You can use your imagination and build just about anything. I've enjoyed building the Dragster, collision car, gravity fan, and balloon powered plane.This product has already given my grandson hours of fun in the few days he has had it. I love watching what he can make with the pieces. He is quite amazing!!”
“The book contains lots of good information about physics, but my son and I built the catapult, and we were disappointed. The instructions are hard to read, with poor resolution photos. The pieces do not hold together well. The catapult collapsed with the first launch. We havne't built the other models yet, but I'm almost certain it won't be any better.”
“As other 1 and 2 star reviews have pointed out, the pieces of this kit are poorly produced, and do not fit together well. The builds are poorly designed, and have little strength. The finished builds fall apart when played with, particularly the catapult. Others have also mentioned the poor instruction booklet, at least I was able to find that online as a pdf and could enlarge it on my laptop.”
