Thames & Kosmos Roller Coaster Engineering Kit | STEM Toys for Kids Age 6+ | Educational Science Experiment Kit | Build & Learn Physics, Force & Motion | Fun for Boys & Girls | Perfect for Gifting

I wasn't sure if this would be too much for a 7 year old but he loves rollercoasters and building so figured we could build with him if needed. The step by step instructions were very helpful and after the first 2 simpler builds that were straight and a hill, my son was able to build this mostly by himself. He tested and manipulated the loops to get it working and then explored putting coins in the carriage to weight it as different positions and weights. It was really good fun and unintentionally educational. The cost was definitely worth it. As he gets older reading the book and the controlled experiments will be great. For now it is fun.

My 9 yr old son’s favourite toy by far. Well made, instructed and lots of possibilities. Accompanying book is interesting and educational as well

parts can snap or a bit flimsy but overall its fun and a part are good quality just the track that lets this down

Bought for my nephew. Absolutely loves it. Hours of fun!.

Bought for 9 year son for Christmas. He loves it.

The coaster engineering kit looks good. I have bought the kit for my granddaughter for Xmas.

Looks good on box. Christmas present for my son so not opened yet.

It is nice for little rollercoaster fans once set up, but takes some time and definitely requires adult help to build. The spring function to set the roller coaster off doesn’t work very well so they have to manually pull it around making it less fun and definitely not what we expected. Some of the part also came damaged. I would have probably sent it back if it was not for my little one really wanting it.

Easy to assemble and my kid(5) loves it. The posts come out easily but theyre mass produced plastic parts

un ennui avec la voiture..... retour du produit et tout s'est fait vite et bien.... merci à amazon...remboursée, j'ai recommandé le même produit devant l'insistance de mon petit fils car il adore ce jeu...... attention article assez fragile , à manipuler avec douceur....., sinon très bien pensé!!!!

My grandson loves this. He recieved it for Christmas.

Bought as a gift and the grandchildren love it ! Very versatile and can change the track for different outcomes ! The package came on time and was not damaged! Great Stem product and awesome product for the engineer in the family! Overall great quality material and would recommend it for purchasing !!

As I tried to illustrate in the pictures, I didn't follow the typical building model. However, my complains are not caused by that. My biggest one is the track system on the "cars", they are not tight enough and tend to wobble around, reminding me of early hot wheels tracks that would create too much bouncing and movement in the structure to be sound and therefore stay together. The only other would be the consistency of the part fittings. Most fit together nicely and stay together, however you do run across those parts with loose fittings here and there which I salt with hot glue. Overall, this is a great product and much fun for kids.
