The Ninja thirsty is such a cool appliance !  No need to buy flavored sparkling water anymore.  Make it right at home with a push of a button .  Lets me be in control of the amount of fizz and flavor that I want.  Also has a size selector so there is no waste.  Many flavors to choose from as well.  Set up was easy.  Just attach the co2 and fill the water reservoir and you’re set to go!
