Well, yeah. Adding a cool metal thing to a hot liquid thing doesn't make that hot liquid thing stay warm longer. It's the same amount of net heat energy, minus the minor averaging effect the slightly cooler metal thing will impart. They're pretty but the claim of making your coffee remain hot twice as long is just silly.
