I was fortunate enough to win this Nutri Bullet. I had saved using it until by former blender stopped working after having it for almost 5 years. 
I make raw veggie shakes and my other cheap blender would liquefy the shakes and they were great. But this Magic Bullet has only one setting and leaves my lemons with the rinds and celery all chunky, no matter how many times I mix it or how long I leave it blending. Will be buying another cheap, reliable blender which actually liquefies smoothies.
