The Shake 'N Go! is a great size for a single serving of a protein shake, smoothie or any beverage that you need to mix. It mixes quickly, you can crush ice for your drink is nice and cold, and it's small enough so you can take it anywhere. I use it for a quick protein meal shake when I'm in a hurry. I am looking to buy another container so that others can have a quick shake also without having to empty the container that it comes with. Great gift idea! Shake 'N Go! is the perfect solution if you do not have time to eat, but need a healthy, energizing shake to take with you anywhere. Mix and drink from the same bottle 16 oz. Shred ice instantly! Compact size fits auto cupholders. It connects to any standard outlet. High power features of the base motor and splash resistant, flip straw top cap.
