I absolutely love this cup. I bought one in blue for my boyfriend, who drinks tons of soda but likes to put ice in it, and after seeing how much he enjoyed it I tried it & ended up buying a purple one for myself, even though the sale had ended and the price was higher. It was totally worth it. It's an excellent, high-quality product; the double walls are barely noticeable, except when you realize that even in an 80-degree house with four ice cubes in the cup, there is NO sweating. It keeps your stuff cold; the grip is comfortable, and clumsy me has NEVER dropped it; the plastic is really easy to clean (note: I don't have a dishwasher, so I hand-rinse -- no soap necessary, even dried-on Coca-Cola spots rinse right off). The stirrer shape on the end of the straw is ingenious, and the rubber seal inside the lid combined with the snug (but absolutely not inconvenient) straw opening makes spilling a thing of the past, even when the cup is ON ITS SIDE. This is an incredible product, made with the consumer in mind, not just the money; would buy again x1000.
