Rated 4.6 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by Very pleased with product Was very pleased with this blender...and the price was very good. You can put large cubes of ice and it will crush it very fine...use it for smoothies and shakes. One very important note to remember the blades are EXTREMELY very careful. February 25, 2015
Rated 1.0 out of 5.0 by Overall defect I did research and found only great reviews. It makes snow ice perfectly and blends smoothies to perfection. However, after four mornings of smoothies, I noticed the nylon connector that secures the motor to the shaft is being smuushed out of shape by centrifugal force. The connector has lost its torx shape and now resembles octopus arms. It is only a matter of days or weeks before this fitting will be stripped and the Ninja will be in the trashcan. There is no replacement part. Do not buy this. April 30, 2011
Rated 4.0 out of 5.0 by Very Good! We used this over the week end for blending, crushing, chopping and mixing purpose and it passed all the tests :) Bit difficult to clean the lid and noisy too! January 20, 2015
Rated 5.0 out of 5.0 by Love this Unit! I've had mine for over two years and use it every day. Best smoothie maker ever and the motor is quite strong. I will probably buy the new model when this one wears out. Highly recommended!! March 22, 2012
Rated 5.0 out of 5.0 by Exceeded Expectations! Was given as a gift to my son, he was so-so at first. I knew he was on a weight reduction diet. Once he tried it, now he's blending and sharing for everyone. He loves his Ninja! I'm going to buy one next. February 10, 2015
Rated 4.0 out of 5.0 by So far so good. Seems to work well Have not tried to do everything yet but no complaints with the smoothie part or the food processor. February 3, 2015
Rated 5.0 out of 5.0 by love it Makes great smoothies with frozen fruit, so far that is all ive used it for but i did use a friends to make my special cracker meal for fishfry and was so impressed i had to have one. When i read the reviews about blending and crushing ice, well i haven't been disappointed. Will have to sell my foodprocessor and blender now. April 10, 2012
Rated 4.0 out of 5.0 by Has replaced my Magic Bullet I'd probably rate this 4 1/2 stars. Really, really like it - don't love it 100%. I purchased one of these to replace my Magic Bullet. Pros: - Amazing price / value! - Fast and effective - blends through everything without the scraping and stirring and headaches I had with my Magic Bullet - No ice cubes left in my smoothie - there were always cubes left when I used the Magic Bullet - Compact option for a blender Cons: - Not as easy to clean as the Magic Bullet. With several parts (bowl, splash guard with some little crevices, and 2 blades), it's harder to clean than my Bullet. It is dishwasher safe so it's not a big deal if you don't use it daily (which I do) - No serving cups. I never realized how nice it was with the Magic Bullet having the multiple cups in different sizes. I used the small one a lot - there's no equivalent with the Ninja July 10, 2013
