k'nex Thrill Rides-Kraken's Revenge Roller Coaster Building Set-Ages 9+ -Engineering Education Toy

I was really excited about this product when this arrived. It had all the complete parts and I was able to construct it. But to my disappointment, the car does not complete the full loop. I have rebuilt it twice done everything to fix this problem but in vain. It’s very expensive and was a complete waste of money

El producto llego en tiempo, todo de buena calidad y bien, sin embargo al terminar de ensamblar todo, la ultima pieza que es la cuerva que une todo el sistema no venia en el paquete. Solicite el cambio y estoy en espera de mi reembolso para volverlo a comprar. Espero sean profesionales.

I was very excited to share this with my kid for his birthday as I had countless hours of fun as a child with knex. The packaging is fine and the structure/design of the coaster is neat, but the quality is so very poor. The pieces feel cheap now and don't have nearly the same ridgidness as I remember. The parts do not always snap well together especially the tan pieces that connect to the track. Between floppy pieces and loose connections there is so much kinetic energy transferred to the structure that the car won't make it around by itself. They have engineered it so that under perfect circumstances it will barely make it around then supply the kit with cheap parts and loose connecting points making for a disappointing build.This present was for my oldest and I have 4 kids total. I am pretty sad that I'll never buy knex again and even more disappointed that my kids won't get to experience what great products the company used to offer.

I purchased this for my 10 year old son for Christmas 2019 but unfortunately for him it was far from a 5 star review. Before purchasing I routinely read the reviews and I was surprised to see half a dozen or so purchased arrived missing parts. Against my gut feeling, I hoped for the best but ultimately he received an incomplete set (on top of arriving 3 days after Christmas 😣). What an effing bummer guys. He was so disappointed he asked me to just return it. Buy at your own risk! Was looking forward to building it with him 😟

My son loves this until he had to fix it Everytime he put something new together. But the quality is bad. These are NOT normal size k'nex pieces.These are much smaller/thinner and poor quality.Once the coastet is together it is very flimsy and will fall apart VERY easily. My son has spent just as much time fixing it as he did putting it together.I would not buy this again unless it was with regular sized k'nex pieces. It should be advertised that these are much smaller.We own a lot of k'nex and all four of my kids love them. They can't even go back to play with this without having to continue to fix it.
