Title: A styrofoam cup would be better
Review: I purchased this cup last week. As an experiment I decided to fill this bottle up with ice and leave it out for a few hours. When I came back the water was just cool, not cold, and all of the ice melted. I would move on if you want your water cold for more than 30 min.
