Query: Terrible design: assembled it and my son can't even use it

Don't buy this toy unless you want to waste your money!!My husband-to-be assembled this toy and my son was so excited. The moment my son sat on it we knew we'd been scammed out of the money we paid for it. The main problem is the back end is too wide. The wide back end interferes with the backward movement of his legs and therefore there was no way he can propel the scooter forward. The narrow front seat with wide back end is a major design flaw and I find it hard to believe that this toy made it out of the design and testing stages at Hasbro Playskool.Additional problems: The wheels are extremely slippery plastic; it rides too low to the ground, and once assembled it cannot be disassembled, placed back into the box and returned to the store for a refund!
