I read all of the reviews on-line before buying this product. When the package arrived, it was exactly what I was expecting. We set it up in five minutes in the garage. It would have taken only 2, byut we had to put padding under it, per the instructions. (do not place directly on concrete...) Construction and quality both are grat. Our five year old son absolutely loves it. We will be testing it again this weekend when his 2 cousins come over to test it out.
