I was missing a car a first shipment. They sent one out the next day no problem. My boys love it so much they want to get one for me as a birthday gift!
I am not playing with, nor have I opened the box. We are waiting to play until the grandkids visit. But, I trust it will be a wonder for them, and a great memory for us.
My son used this to do his 3rd grade science project and won 2nd place! We had a blast doing it. I would recommend finding a large straight area to do this. My one problem with it was that it was difficult initially for my son to stomp on to release the rocket.
Great toy. It was easy to set up, fill up and release. It was great fun for the kids. They enjoyed watching the car race up the driveway, plus it was great exercise for them to get the car and do it all over again.
