Unfortunately, I agree with all the bad reviews...
Well, I read the reviews and still purchased the set. Shame on me. I was hoping we would be one of the lucky ones to get a good set but we didn't. Not only was it terribly difficult to put together (ours seemed to actually have two incorrect numbers) but it was flimsy and didn't really work at all. The track is much to wobbly to withstand any real momentum that the car gets and Lightning didn't make it around the top of the set even ONE time. Some of the pieces never really clicked properly either - very poorly designed. I also didn't test it until tonight (just 6 days BEFORE Christmas - again, shame on me) so now I have to figure out what to get as the "big" present. Hopefully, I can still get a refund since I waited so long to test it. We definitely received one of the defective sets.
