Ninja Master Prep (QB900B)


This is my best little gadget and I have many. I wanted a Vita Mix since I can remember but it was too expensive while raising a family. I finally got one a few years ago, and it was a big disappointment. It was big, bulky and noisy and it did not do anything special. I used it all the time anyway to make smoothies, it was not much good for anything else.
Then I saw this Ninja on TV and thought it was a gimmick. I finally bought one since I started to hear many good things about it. And it was very affordable.
I can make my refried beans, chop onions and garlic, smoothies and sauces, but my favorite is the take frozen fruit and add some milk or coconut milk and turn it on, it is just about the best frozen dessert you can find, you may not even have to add sugar if your fruit is sweet enough.
I really love this Ninja I use it every day and sometimes twice or three times.
I am thinking of getting another one just in case this one breaks.
