Within five minutes after taking this toy out of the box, my three year old let out a scream and began to cry. He had pinched his finger while lowering the transporter. Five minutes later, I did the same thing to my own finger. Ouch!I continued to fumble around with the awkward levers and buttons and was baffled at the complexity of what should be a simple, straitforward toy. Even my three year old agreed with me when I suggested we bring it back to the store and pick out a different toy.
