Title: Exploding Cups
Review: These work fairly well as a straw cup and we used them for about a year with our daughter. But they leak/spray almost every time you open them and they frequently EXPLODE as the liquid inside gets slightly warmer. The pressure builds inside the cups and after only a minute or two out of the refrigerator they start spitting milk/liquid everywhere. They are very messy and the straw is made of 3 separate pieces so they are hard to keep clean and easy to lose parts.
