La pista solo es compatible con el coche que trae. Tenemos muchos exactamente con la misma numeración y ninguno funciona. Estamos muy descontentos.

buena calidad, es muy suave el polar

My sons first words when he saw this track put together were “This is awesome!”. Initially it took several tries and multiple adjustments to get the car to complete the loops. The car would fly up through the first loop, go up halfway on the second and then fall. While having difficulties with the car provided, we did attempt to try other Hot Wheels brand cars and experienced the same issue of not completing the circuit. This made this particular toy seem as though it was a total dud but then after some adjustments the car began completing the circuit.
A few positive characteristics were the track colors. They were nice and bright and made the set look fun. The lettering on the tracks were a huge help in the assembly process and even made it so that the instructions weren’t even needed.
Some improvement suggestions would be to make the set so that it could be taken apart and folded for storage. The toy pieces lock into place and are unable to be taken apart. While this helps to keep it together and complete, it makes it so that finding a place to store this toy is impossible. The only way to possibly get the pieces apart is by using tools which could possibly break it.
The thrill of the toy seems to have worn out after a couple of times playing with it so that leaves a large toy that can’t be folded sitting around. The concept of this toy is great however the execution in the production of this toy could be improved making it more desirable for both children and parents.

Hot Wheels 4- Loop Crash-Out is a really nice track. It is big (4 loops) but since it is tall, it doesn't take up too much floor space. It folds up easily to store it or move to a different location to play with it. It can easily connect to other hot wheels tracks to add to the fun and it also can be used with other cars.
Now for the cons: Really there is only 1......the batteries. It takes 4 "D" batteries. The first time playing with it I put some brand new brand name batteries in it and got about 20 minutes continuous playtime before we noticed it slowing down a bit. I folded it up and put it away until the next day. Sadly I have no video from day 1 but we were getting almost non-stop loop de loops with only the occasional "accident". That was the last time we got that from the track. What this video shows is what we are dealing with ever since folding it up and unfolding it. The car just doesn't go all the way through. We have tried 2 different sets of batteries of different brands with no change in results. We have looked the track over numerous times to make sure nothing came apart and we cannot find the reason for the sudden change in performance. We have found that if we prop up the support feet under the loops, it will work better but obviously that is not the intended setup of the track.
Overall, the track is really fun and the replay ability is definitely there so we will continue to play with it and I do recommend it. Just wish there was a way to adjust the positioning of the supports. Also, I really hope that Hot Wheels will consider making rechargeable set in the future.
