I previously owned a Nutri-Bullet and decided to go on a smoothie cleanse which I felt required a more substantial device than the Nutri-Bullet.  Not only is it fast and very effective but the clean up is a dream!  And because I don't have to spend a lot of time chopping and prepping, I can make and clean-up in about 12 minutes!  It handles ice like a breeze.  I also like the fact that it creates batches enough to fill 3 16-oz Mason jars so I only have to make my smoothies once a day.
