Query: Breaking, breaking, breaking... DANGER

I am unhappy with this product. I researched and researched and finally chose this as the set for my 3-year old son. I am so disappointed that I wasted my money. My husband has glued tracks, trains and other pieces to this set. They are constantly breaking. On a more serious note: The wheels come off of the trains, they pull off easily, any kid would be tempted to put these metal pieces in their mouths!!!! Beware!
