I love this Nutribullet Blender.  I brought it into the office for a potluck we were having and made office-free margaritas and this blender lasted all day long.  First I want to mention there's a safety feature on it that knows when the blender is on the base correctly.  If not, it will prevent you from starting to blend.  I used it on low to make the margaritas and it blended very nicely.  
The design is sleek and I love the look of the gray.  I had a ton of compliments on the appearance of this appliance. 
Although already very sturdy, it also has suction cups at the base to prevent the blender from moving.  Clean up was a breeze as well.  The parts come apart nicely for cleaning.
