I bought this 2 weeks ago. It is good. One thing I don't like is you have to keep the container with fruits or what ever upside down in to the base. If it is not tight right, there is possibility for leak and also inconvenient to open and serve. I prefer to keep upright when making juice.

I love my Ninja. I use the Nutri Ninja to juice and make protein shakes. It is efficient and fast. However, at the end of the cycle, the juice and protein tend to get warm.

Got this as a gift for a family member bc I have one of my own and I love it. Smoothies every morning with ease. The mixing container is your cup. How Easy Is that. Clean up a breeze. Very powerful machine. Would recommend to anyone.

We bought this blender from Sam's Club in mid January and used it daily for five months. By mid May, the blender would not start consistently. To run, four plastic tabs on the blender jar must be engaged in corresponding receivers in the base, and the jar pushed down to start. After five months the plastic tabs on the jar had been chipped down so they were not engaging the switches. SharkNinja replaced the jar under warranty. Within a week, we noticed the plastic tabs on the new jar were starting to chip off as well. We discovered one of the safety switches had worn a ramp in the plastic, and was chipping plastic from the tabs when the jar was pushed down to start. Today, even the new jar has to be rotated, sometimes, two or more times to find a position in which it will run. SharkNinja offered to replace the blender for over $50 shipped. I asked if I could pay a discounted price for a model with a start/stop switch, but the offer was only on the same model. This poor engineering renders an otherwise good blender, useless. You would be better served finding a blender that uses a start stop switch and avoid this badly designed push down to start unit. My $18 Hamilton Beach Personal Blender lasted longer than this unit.

Bought the Nutri Ninja to put some interest into my fruit & vegetable intake. The machine works well as advertised & has the power to mix any concoction you can think of, within reason. I enjoy mixing myself a cool drink twice a day & that seems to cut down on my excessive appetite already.

Compact and effective blender unit. I bought this to replace my larger blender and it is perfect. I love the Auto IQ technology and the fact that I can do what I need with it and taking up the least amount of space on my countertop. Low noise and easy to use.

We are very happy with our Nutrition Ninja Auto iQ blender. We use it constantly and have had no problems. The different sizes of cups and and the lids that come with them are so convenient. It’s not quiet while blending but I have yet to find one quieter out on the market.

I have an older Ninja model but really wanted something to make smaller portioned smoothies and loved the features on the single serve. The to-go cups are a huge bonus. I can prep in the evening and add ice, blend and go in less than 5 minutes in the morning. Have had this about a month and use it several times a week with no problems. Even though I can't use all of the recipes it comes with due to diet restrictions, they do inspire good ideas. Can't wait for the summer when I can really have some fun with cold drinks and smoothies

I like this blender. Even though it comes with 3 different size cups, I do wish I would’ve gotten one with a pitcher. It is pretty loud but not a deal breaker. The suction on the bottom is good so it stays in place when blending as it is powerful. Overall, I like it.

After having a cheaper one-serving blender prior to this, I knew right out of the box I knew I was going to like this. Blends everything smooth as butter within seconds. No more rough texture, dirty feeling drinks. I expected 1000 watts to be deafening and was pleasantly surprised that it wasn't nearly as loud as my regular household blender. However, there were a few things I noticed right off the bat. 1) When you load your cup and twist the blade on, you have to tap your food down or it won't catch in the blender blades. 2) There is no measurement markings on the sides of the cups. This was disappointing because I like to measure my intake and these cups are a free for all. 3) I like using a straw to drink from the bottom of the cup since sometimes juice has a slight foam that settles on the top after mixing. Using a straw is impossible with the larger cup and the other two sizes are awkward due to the large opening. All in all, I really like this blender and wish I'd purchased it long ago!
