IT LOSES PIECES

Until a few days ago I would have given this product 4 stars. The pin that holds the lid on keeps working its way out. It's easy to push back into place, but I may miss it one day, and that would be the end of the cup. Then the gasket that seals the drinking spout disappeared, so end of the cup. It still stays cold, but unless it's upright, it leaks.
