The blender functions well.  You must have the blender near an A/C power outlet or use an extension cord; the provided A/C power cord is short. The open "windows" along the metal enclosure around the blade help to flush water through to clean the blade area.  It is a good design.

To Manufacturers:  Please provide a video demonstrating how to pack all the components (including the clear plastic container with lid) back into the box.  This will be helpful for those of us who keep the equipment in the original packing box.
