Bought the bullet-was not impressed. Got the ninja and use it all the time. Best appliance in the kitchen beside the kitchencraft mixer.
I replaced my bullet with the Ninja and I love it!! I looked at the Vita-Mix and thought it too expensive, plus I didn't really need an honest-to-goodness juicer. I make smoothies all the time and even include some greens in them - bananas hide the taste of almost anything else.
I also used the Ninja this summer to make Gazpacho. It was delicious and so easy. I dusted off my 40 year old Oster blender - still working well and in beautiful shape - and gave it to a friend who needed a blender.
As the weather turns to winter I expect to start using the bread dough feature on the Ninja, too. BTW, if you are interested in this product it was significantly less expensive at my local BJ's than the online place I actually bought it.
Learn from my mistake!
