Here is a write-up on this toy from my previous website. These sets are alot of fun, the cars and trucks are well made and it is amazing---in all the sets of Switch 'N Go I have created, I have yet to have a bad motor or one I could not fix. The dump trucks can break at some weak points, but one of mine I repaired and you cannot notice it. You really need to play these on a tile, linoleum or hardwood floor, as they are just too large to run on a table.
