I had the smaller less powerful one whcih I already thought was great but this one is even better which I thought was impossible. I bought this blender because it was bigger than my other Ninja Blender. This one is exceptional and worth the price. It blends and liquifies to perfection. I use it with the smoothie option and it exceeded my expectations. It is worth every penny.

Just the upgrade I needed. Very powerful blender. I had an older version that lasted me a while it still works but I wanted a new one. Caught it on sale Mother's Day weekend and couldn't pass it up

An excellent in-home blender that’s perfectly balanced between simplicity and ingenuity. This series is both easy to use, yet not as haphazard and boring as most other models. Your ingredients will be expertly broken down in the blink of an eye. Fruits, veggies, ice, you name it it’s getting sliced and diced by the sharp blades of this Ninja. The only drawback is that it’s pretty noisy, but that’s a minor inconvenience when you think of how much power the Ninja Duo packs to get your ingredients broken down. The smart IQ feature makes it easy to push a button and watch it go. Definitely my favorite purchase of my household appliances thus far.

So far I really like THIS Nina blender. This is my third blender in less than two years. The first still works it just wasn’t great at making smoothies. The second, a quiet blender, had all kinds of issues. I’ve now used this one about 10-15 times to make smoothies. Positives- It is not as loud as some. Because of the three tier blade it blends super quick. It is easy to secure the blender to the base and remove. I have yet to have any issues with leaks. The lid secures easily so I am not concerned with food coming out the top. It has a safety feature that if not assembled properly it will not start. Rinses off easily. Less positive - though it does have a pour spout that opens on the lid, pouring smoothies can be challenging, especially if they are kind of thick. The blender is all plastic which so far has not been an issue. I worry that it could crack or have premature wear.

The blender and dual drink/shake mixer works well. We like spinach in our shakes, but hate those little flakes. With this system there are no flakes, everything is pulverized so we get the full nutritional value without the little chunks. The price is a bit steep, but it seems very well made. Time will tell.

This Ninja is not my first one. I have had a Ninja single serve blender for several years! Always loved it, but it got a little hard to lock on to base, so I just got a new one. This is great chopper, blender, smoothie maker; all in record time!! I love it! It’s wonderful to chop veggies,cooked meat, etc to make salads. Be very careful washing the tall part with the 3 blades!

So much quicker and easier to make smoothies than a regular blender. A word of warning: there's a reason it's called "Ninja". Make extra sure you know where your fingers are in relation to the blades at all times...they are quite unforgiving if you touch one by accident while loading it into the dishwasher.

Had to get a new base unit sent out covered by warranty because the switch that the cups activate when you twist it on the base, was assembled in the wrong direction and not allowing the cups to activate the system. New base was shipped and received in about 2 days. Excellent customer service from Ninja company... Awesome unit!

I bought this primarily to make smoothies, it does not liquefy the ingredients. Has many chunks and grit.

Based on an excellent price, I purchased to have a blender at the lake. It operated very different than my older Ninja. The ice crush, which I use for slushy drinks, pulses. It does not run continuously. The other settings run for 60 seconds then turn off. To get slushies and blended ice drinks such as a daiquiri, super smooth, I run the blender for several minutes. I don't want to stand by the blender to constantly restart the blender. I returned the blender.
