Hello Everybody, for my son man I bought this set. The product may not be recommended by me. It consists of cheap hard plastic. I fear it will not survive for a long time. The wheels must be properly rum be such that the gears engage. This is not really intuitive. Unfortunately, I know of no higher quality product, but it should be in my opinion the finger.
For the money you will have an ice cream with the kids prefer. Greeting Patrick
