My grand kids feel this is the best gift they have received.Racetracks are easy to snap together and are very easy to store. Best part is that this product comes with 2 powerful cars that do not disappoint, unlike other brands. My grand kids have been able to creatively establish new track shapes for additional fun. You can keep stretching tracks all over the house if you have more than one. These cars require 2 AAA batteries which provides a lot of speed for curvy tracks.
