5 Sets in 1

Comments about K'NEX Cosmic Quest Building Set:

Well the Cosmic Quest Building Set by K'NEX may be a small set at 126 pieces only but there are five different ideas included for creations. So yes five ideas are included to build various cosmic creatures and rides. You can only build one at a time then you have to take it apart to build something else, but at least there are directions for all five creations. My boys of course loved the cosmic rides, especially the motorcycle which hasn't been taken apart yet to build the next thing. Yes the motorcycle does actually zoom across the floor! You get all sorts of pieces in this set so you can follow their directions or come up with your own creations, which my boys will do eventually. I love though that this set is affordable and includes some pieces they haven't built with before. If you have other K'NEX pieces at home you could also use them to build the other creations at the same time. I received this product to review in exchange for sharing my honest opinion.


5 great space building models

Comments about K'NEX Cosmic Quest Building Set:

*Product received as a review* This K'NEX set is a 126 piece set that features five building ideas to create the ultimate space adventure. Ideas include a Mars rover, hover craft, alien, space suit man and a moon bike. My 7 year old enjoyed building as the instructions were fairly simple and minimal with only 4 steps. Vehicles with wheels actually move so children will also have fun once models are built. The only downfall with this set is once the model is built it will need to be taken apart to build the next idea. If you have additional K'NEX then you can definitely build what is shown or children can use their imaginations. An affordable K'NEX building set!


My kids have had a blast with this set!

Comments about K'NEX Cosmic Quest Building Set:

My son, who is 10, had a blast building the 5 ideas that they supply you with in the instruction booklet. I will refer to them by what he named them. There is a Robot, Spaceship, Alien, Rover and Motorcycle Cruiser. He built the robot and actually shocked me on how fast he built it. He said it was so easy. He said he choose that one because he really liked the red laser that the robot was holding. What I love is that they give you suggestions and instructions on things to build, but it doesn't stop there. My kids can then use their imaginations and create their own. We made our own car and motorcycle too with the set. They can literally spend hours sitting and creating things with their K'NEX.


Just your average K'Nex product.

Comments about K'NEX Cosmic Quest Building Set:

I received this set not to long ago and I am happy with my purchase. The set include 5 buildable models, but you may only build one at a time. The models consists of 2 aliens and 3 vehicles. Personally, I think that lacks of the "comic" theme. I've never been to space, but I'm sure there are no bikes there. The models were simple and easy to build, and the instructions were nice and clear. The value is not a must have; much pieces are your typical K'Nex pieces, and those pieces are indeed high quality. I don't think this set is a must have, but if you are asking for a good set with just a little money in your pocket, this is a safe buy, and your every day, average K'Nex product.
