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 !!

Hours of fun and creativity.

My grandson enjoyed assembling this product. He liked the fact that it can be used to assemble in various manners

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.

It was great. Easy instructions and many paths to build. Would highly recommend

Bought this for my nephew and he loves it!

Great birthday gift for kids

Lots of fun. Plastic is okay but already showing signs of fatigue. Had to glue one of the carts together because it cracked on all four threads mounts after coming off track first day.
