Bests & Worsts Reviews from Amazon

We had borrowed one of these from a friend and had it for about 3 years but returned it when they had a new kid. It was great! This new one is garbage. My husband who is an aerospace and mechanical engineer by trade who also builds race cars for fun cannot make this thing run smooth. It is loud, rattling and the quality of the plastic cheaper than the original model (which was only made a few years ago). I give it one star because my kids still love it, I just can’t stand pushing it with all the racket!
