It Hasn't Come Off!

I bought this as kind of a novelty item to protect my white Radian stainless bottle. Little did I know that I would rarely ever use the bottle without it! It has a grip on the bottom that is perfect for hard surface placement, and a comfortable feel in the hand. I definitely would be another for future Blender Bottles.
