When we got home we opened up the box and started to set up its contents. The diagram was descriptive enough for me to assemble the set and it went together pretty quickly. I am not, however, happy with the set for several reasons.

First, the tracks don't all snap together. Some slide together into a groove, but others just lay or overlap one another. The places that overlap easily slide apart when children try to drive the cars over that section. The whole set separates in three places. Who wants to drive their car over a track the keeps separating?

Secondly, the cars don't fit correctly into the track. It is almost as if they made these tracks without even measuring the width of the cars. The wheels drive on the ridge of the track instead of securely inside of the track--the way one would think they should.

Third, the chain reactions that are supposed to be set off when the car hits into the trigger points do not set off the chain reactions as promised. The first trigger does push the car onto the track, however, the car never reaches the second trigger point because the tracks separate and the car is sent rushing across the living room floor and under the couch rather than acroos the track.   My son was completely frustrated with this set. I brought it back to the store and allowed him to pick out another toy.   I do not recommend purchasing this toy at all.
