Cons: should be made to work with all cars, should be made with the ability to expand
Got it for our 3-1/2 year old son for Christmas. He likes it. As others have stated, it doesn't work with all cars, but it does work with some that are not made specific for the track. He loved it and it was easy to set up. I don't think the quality is bad at all despite what some of the other reviews said. I read about battery issues, so I bought the rechargeables and haven;t had to charge them yet and it's more than 2 weeks later. Can;t go wrong for the money.
I was very impressed with the speed of the delivery time, also the Hot Wheels track was an awesome present for my son. I will order from Mattel again. I was very impressed with the service.
It was great to be able to buy this track set after every other store was sold out at christmas time. The product came in a timely fashion without any issues. Good job Mattel on giving customer another avenue to get your products.
