I purchased this toy for my son who is 15 months old, and he just loves it! There is so much fun to be had with this between the loop de loop and the regular race track, he is constantly drawn to it. My 4 year old daughter loves playing with this as well. She will race the cars down the tracks to see who finishes first. And we recently had a party and all the other kids were drawn to this toy, all ages.
And, I can speak that the toy is quite durable. I was a bit nervous about having the loop de loop always exposed, but it has withheld my son sitting on it and multiple falls onto the ground.
The only difficult thing about this toy is the storage. Since it doesn't fold up, you have to have a place to store it, but that is an issue with any toy this size.
I would definitely recommend this to friends and family and I know it will be a gift for some special kids in the near future as well. We love this toy at our house!!!
Also, note that the race car wheelies are a bit harder to use on the loop de loop track. Because the stopper holds them up using the front of the car as leverage, they often fall off the track before releasing them. However, the ones that come with the track are great and even our dump truck wheelie works great on the loop de loop! Again, I cannot say enough positive things about this toy. It was even easy to assemble!!!
