Both the Nutribullet and magic bullet are pretty much the same thing however they are a bit different from each other.
The only real difference between the Nutribullet and magic bullet is the motor size and power of each one.
The Magic Bullet has a smaller motor that is only 250 Watts while the Nutribullet has a more powerful 600 watt motor.
Another difference between the Nutribullet and magic bullet is that the Magic Bullet includes more accessories, which is convenient over purchasing mixing cups separately.
But other than the motor size and the accessories that each one contains the Magic Bullet and Nutribullet are almost the same.
