Query: Awful! Leaks terribly!

I just bought this cup and gave it to my daughter this morning - with milk in it. Should have tried just water first. The cup was tipped over on the carpet and was laying in a huge puddle of milk! I took it into the kitchen, held it over the sink, and milk poured out of the straw. I took the cup apart and put all the pieces back together with the same result. It was literally like pouring milk out of a straw. Don't waste your money.
