Greatest cup in the world!

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.
