Query: What a piece of CRAP!

I can't believe I paid $40 for this poor excuse for a race track. How can they get away with the commericals portraying this race track as the best race track ever. The tunnel set up was a real big pain in the ###. We managed to get the charger to work 4 times, with the car flipping off the track in the first corner every time. My grandson is so dissapointed, unfortunately he still believes everything he sees on TV.
