Our old blender stick finally broke after too many years to remember.  Bought this blender stick because of the stainless steel bottom.  It is so easy to clean.  Just disconnect the blade section from the motor section and rinse it off.  Does a great job of crushing the ice and mixing various ingredients.  I know the 2-button system is a safety feature but I do find it a little awkward to have to press both buttons to get it started.  STILL LOVE IT THOUGH!
