Well, I have a magic bullet too & I
it! It sounds like locowhiteperson did possibly get a "bad" one. Mine came with the different size bullets to make the small size & large size drink and then it also came with a blender attachment to make several servings.
The only negative I've heard is from other people that burned the motor out from letting it run too long....you're only supposed to let it run for more than a minute at a time - but that's in the instructions.
Ever since I got mine, I use it at least 3 times a day and the shakes are cold & delicious. YUM!!
Now, I have put crushed ice in it, but not frozen bananas....maybe the nanners were too hard to crunch up....I've had frozen bananas before that were as hard as a huge rock.
