Great product and the tumblers that are included are an added bonus !  Do we really need a blender with 10 buttons and 10 different words on it ? No!! This one is simple, easy to work and has only 2 buttons and five speeds via a dial from 1-5!  This machine is not only powerful but sleek and stylish as well with its stainless steel facade.  The over-sized 72oz container allows for blending large batches and the additional single serve bonus cups provide the convenience of not only drinking from but blending from as well.  The cord wrap is a bonus feature as well, no more cords cluttering up counters when not in use.  Oh and let’s not forget the suction cup feet, no more accidental spills cause this baby is going anywhere.  Over all this blender is loaded with features.
