I bought a Magic Bullet a month ago and I use it almost everyday. I use it mostly for making smoothies. I just dump everything in the big cup and it blends everything in like 30 seconds or less. Clean up is easy too..just wash the cup and the blade. I don't think I'd like using a full size blender only cuz I really dislike the cleaning part.
It's great for other stuff as well such as grinding spices, coffee, and chopping onions etc. Only thing I found that I dislike, it's not made for shredding cheese. It will get all clumped up.
