I have the NutriBullet 900 series. It grinds everything so fine you can drink it with a straw. From what I understand the original Magic Bullet is not very powerful. There is a newer model than what I have that even heats things so you can turn whatever you blend into a soup. I just heat my "soup" mixtures in the micro, but I mostly like it for cold stuff. I like to use frozen fruit, plain Greek yogurt, etc. and make wonderful smoothies. I've had mine for a couple of years and use it several times a week and it is still going strong. I highly recommend it!
