### ⭐⭐⭐⭐⭐ Hours of Fun!! But be prepared, the car won't always make it around the longer track "plans"
*by J***I on December 26, 2023*

We ordered this for my 6 year old for Christmas and honestly do not regret it at all! We spent HOURS playing with this. Not only following the suggested track options but he wanted to get creative and come up with ideas to create his own tracks as well. So I do LOVE this challenges his mind and keeps him off of electronics! However, even after carefully following instructions, we found that car will not always make it through the long track "plans/ideas" that book has suggested (video included). I have videos of other tracks where the car did succeed, however it will only allow me to upload one video. I included a photo showing that the 6 piece flat "track" can also be made into a 4 piece set which is sold as a separate kit, so if you are torn on which one to purchase, know that the bigger kit CAN be made smaller (and also includes more pieces for more options). We found we had the most success of the car making it through the track, if we started with marble already on the car. I helped my 6 year figure out his ideas by showing him to trace along the lines on the insert pieces to see if his planned track would work or "dead end". All in all, it was a lot of and good quality time together. It is definitely something that he is not ready to do solo at this point, but I feel it is good to help him problem solve and would recommend this product. But I will reiterate, that the car doesn't always make it through each course. We also went ahead and purchased an additional car, Incase his broke. But as of day two, the new car is still in the closet.
