I love this cup. It is my go to cup, especially living in Arizona. It is so hot here, and ice water is a must. This cup can sit in the car for hours while I am out shopping, and the ice is still in the cup. Amazing is what I describe this cup to be. I love taking it out with me at the pool. My drink stays cold for hours. The convenient holder makes it easier to fill and transport the cup. I recommend this cup for anyone who like ice cold drinks.
