While I love my Vitamix blender and use it everyday for smoothies, this cup is such an awkward size I've only used it once. I bought it to drink my smoothie in car on way to work, and keep it cold. But normal size straws are too short and fall inside, and I haven't been able to find any extra long straws. It's too dangerous to try to tip this cup back to drink from while driving, and just awkward overall to drink from even at home.  It should come with a long reusable straw.  For the price, and the quality of Vitamix blenders, I expected better.
