I will definitely be getting one of these for a few friends for Valentine's Day gifts. I will also put this one on my "what to give somebody who has everything" list. This is great!! It would make a delightful gift for a smoothie enthusiast who makes a smoothie at home for drinking at work or on a walking trail. No worries about keeping it mixed or cold. It would also be a great cup to take to Jamba Juice or other smoothie cafes. You would be helping the environment with reusable mug as well as keeping your drink cold and mixed.
