    A great product for STEM to problem solve and learn basics physics.
    For $10 this product is a steal. My 12 year old built it with a little help from his 10 year old brother. The car will go around several times without need to stop it, and all of the younger siblings love it. We did experiment with the length of the plastic chain, and we had 2 links left over. This was ideal for maximizing the number of go arounds. I got this to get my kids off their electronics and it worked for 2 hours... There is a design flaw, which causes the first guide to be unable to hold the plastic chain in place for the cars catcher to line up properly. When the car reaches the top, it can’t be released and stops the chain from moving. I imagine one could burn out the motor or break parts. This brings me to ponder, why this is recommended for any child under 9? Back to the flaw I think this happens due to the strain on a single connector on the track. After one day it is already torquing. 3 Extra parts at this point would improve the stability. All this being said, this set exceeded all expectations, and I’m a little confused by all of the negative comments.

    This is a super fun Knex set. However too complicated as an independent build for our 9 year old dragon loving daughter. The instructions aren’t all that clear, and it took my husband and I around 5 hours helping her assemble.
    Once it is up and running, it is entertaining! We definitely won’t be disassembling this set because it took so darn long to put together.

    Reviewed in the United States on May 25, 2020
    When all said and done - great value and it does work! It just takes lots of patience and breaks in between. Definitely not for kids, not the assembly anyways. The tracks require a bit of bending and twisting. I had a few small pieces leftover so I probably didn’t do a perfect job but it WORKS! Good luck!!
