X.O.
I have both the Magic Bullet and the Nutribullet. The Nutribullet has larger cups, so you can blend more at once. I have had it for about a month and am making smoothies about twice a day for myself, and twice a day again for my husband. I haven't used my Magic Bullet since getting the Nutribullet, and in fact, just posted it on Freecycle today.
I do think that the info in the Nutribullet's recipe book is better, and we also bought one of the companion boooks that was offered. So far with doing the Nutriblasts and Weight Watchers I am down about 12 lbs in 5 weeks, and I have much more energy than I did (and I was eating lots of fruits and veggies even before I started this.)
