K'NEX Thrill Rides – Cobweb Curse Roller Coaster Building Set – 473Piece – Ages 9+ Construction Educational Toy Building Set

My 11 year old loves this item. He put it together in a few hours and is very proud of the result. it's a cool little coaster. we'll leave it assembled for a while and put it away then probably build it again some other time. the only thing i wish this set could do is to build more than one configuration of the coaster. I knew it couldn't when i bought it but still think it's cool.

Building set is more challenging than LEGO sets. Had a great time helping (as a checker) my son to put it together. It requires finger strength to snap the pieces together. Seems more suitable for teenagers. My son learned a little about structural engineering and energy conversions. Highly recommended.

Entry level build and fun for kids. The instructions are easy to follow but when you get to bending the track installation portion, some of the peices do not stay connected; i had to superglue some of the peieces that had stress from the track bending. But the biggest complaint would be that the chain will go off track and get stuck at the motor wheel every so often.

Really fun toy and easy to put together. Pictures were clean on what to do. Didn’t appear to have any extra pieces so if you lose any of them it makes it difficult.

First of all, my son loves this toy and he is excited to see the roller coaster running.Now onto the bad. The track is too flexy and some of the supporting pieces keep loosening. The chain lift runs rough and gets stuck every 3 to 4 runs.Building it up is the most fun part but then it gets frustrating to get it running smoothly

I purchased 3 different sets of those types of roller coasters. First two (one by schwarz and one by k’nex) were a disaster. Had missing pieces, not easy to assemble, and most important did not work at the end - got stuck, chain did not work etc. this is the one that works! Had all parts, structure is very steady, chain works and cars go all the way through. Very exiting!

The media could not be loaded. My 8 year old had good fun doing this build. It is her very first motorized set. While it was a little bit challenging for her to get the tracks on, Ultimately she found the effort well worth it, as the car started running on the tracks.

My son got this for Christmas. We woke up at 5 to open gifts and then I went back to sleep and hr later. When I woke up at 8 my son was done assembling it and it was running. Perfect for children interested in robotics, and crafts like assembling and building.
