I am a behaviour consultant I buy lots of toys and my toys get played with alot. Car ramp toys are always a fun favorite. This one is plasitc and not very stable. As a result the cars often get stuck when going down. I recently found a wooden car ramp at the second hand store that was more stable and higher quality. it was missing the cars. I was able to take the cars form this toy and use them with the used wooden ramp and they work great. if you are wondering if its worth it to pay more for the wooden higher quality car ramp it is.
