“I like that it holds my venti cup from starbucks. It keeps it cold until I am finished. But, I have lost lids from it as they sometimes just pop off. Thinking of the environment, the recycle cups would probably work better in it anyway. The silicone top that hold the cup has made it difficult to remove the cup and I end up pulling the whole thing off in order to get rid of the cup. Otherwise, it does what it says in keeping ice even for the slowest drinkers. Just wish there were some improvements for fit. I'm afraid to try it with a grande cup.”
