I have owned my vita mix for A2500 for almost 3 years. I mainly make shakes in it, by that I mean 2-3 shakes a day, everyday, for all 3 years I have owned it. It has never missed a beat. The container is always clean and I have had no issues with any aspect of this blender. My shakes always include frozen fruit, oats, powder, and/or ice. Just as good as the day I bought it.
