Query: Not worth the effort

While the wood products we have purchased by the same company, mostly puzzles, are wonderful, this item is not. It was difficult to assemble, it doesn't stay together while playing with it, and my 3-year old son only became impatient with it, rather than enjoy playing with it. We opted later for a plastic firetruck, that a year later, he still plays with.
