Ordered as a gift for 11 yr old grandson. All parts were perfect and he had it together in less Than 3 hours. Really enjoyed it and now sits on his dresser.
Quality made small working model. Give it some heat for about 30seconds and it starts running. I like to show the grandkids.
So I need to redo my review. The first engine I received would not run, after starting the return process and leaving a negative review I received a box at my door. It was a replacement engine as well as a pocket sized engine that both run flawlessly. The first engine must have been a simple fluke. Customer service is out of this world !!
It worked with regular rubbing alcohol. It was just amazing.
