I received this Ninja "Thirsti" a little over a month ago and I absolutely love it... ❤️  I can put my soda or sparkling water in it and it keeps it fresh, fizzi and cold even overnight.  My coffee stays hot all day which is great for when I am on the road in the car. It fits in the cup holder perfectly. Ice stays frozen overnight as well. LOVE, LOVE,LOVE this which is not surprising I love all my Ninja products...
