Query: Back to Basics SE2000B Smoothie Maker

This is the most advanced form of blender for making smoothies or frozen cocktails I have ever encountered. The tap on the jar is a great addition, but my favorite feature is the stir stick that is essential to making a successful smoothie or frozen concoction. This feature alone precludes the need to stop blending and scraping the jar to mix up the contents. The jar has measuring marks for adding ingredients in the correct proportions to make a very successful smoothie or frozen cocktail. The design of this item is excellent and the construction is robust, as evidenced by the fact that it has held up for over six months after daily use and daily cleaning. That is the reason I purchased two additional units in order to provide for replacement of my original item when that time comes. I never want to be without one of these smoothie makers.
