Habanero puree for chili, blending chunky salsa (pulse only for this), or breakfast smoothies... I can now say it works great for any of the above

It’s a really good blender and makes a really good frappuchino and Ice Cream

I love it!!! it blends anything in seconds. It’s great valve for the price

This is a review of the Ninja Blender Duo with Auto-IQ Model BN751. Ninja makes a ton of models all with different features and container options. It can be daunting to decide which model is best for you. This is a new model with the 72 oz main container, and 2 X 24 oz small jars sharing a separate screw on blade assembly just for the small jars. The similar Model BL641 has a 32 oz and a 24 oz for the smaller container with the 72 oz main unit. Then there is the BL 621 with 2 x 16 oz smaller containers, a 72 oz main container, and an 1100 watt motor. This BN751 is advertised as having a 1400 watt Peak Watt motor. Ironically, when you turn the motor base over, it clearly is printed as 1200 watts. The Peak power rating is most likely advertising. Are we confused yet? As far as using the device, you have to make a decision to use the main 72 oz jar or a smaller 24 oz jar using a separate blade assembly to fit the smaller jars. I tried the smaller jar for a single serve margarita. I added 3 oz (total) of mix and tequila with some ice cubes and put it on the base and used one of the Auto IQ functions (Smoothie). It starts a routine of blending then stopping for the ice and contents to drop, then repeats that routine several times. You simply let it do its thing and you can walk away as it will stop itself. The results were superb! The ice was finely chopped and the whole mixture had that light airy consistency of a bar cocktail. Using the larger 72 oz jar you need to get used to the lid. It just doesn’t pressure fit on the jar. You need to align the arrows on the lid with the arrow on the jar, hold the lid down while you move the handle down to lock the lid to the jar. It’s secure, but it takes two hands for most to complete the task. To remove the lid, there is a “release” button to allow its removal. Luckily there is a nice spout in the corner you can raise the cover on and pour out your contents. I do miss a smaller opening in the center of the lid where you can add ingredients like ice while blending. Because the lid acts as a support for the tall blade assembly that opening in the lid is not going to happen. Also if you have a really thick mixture and it won’t pour out of the spout, you will need to remove the lid and the tall blade assembly before trying to tilt the jar and pour. That can be a little messy as well as keeping your fingers away from the blades as you remove them and lay them somewhere. The lid assembly must be locked in place on the jar and the jar twist locked to the base before the unit will operate. If things are not locked or twisted correctly, the panel lights will continue to flash preventing the machine from starting, nice safety feature. It is ingenious how the motor assembly knows if you are using the large jar or a small jar on the motor. The small jars will allow the “extraction” function, while the large jar will not. Extraction is for tough, leafy, or fibrous fruits including their seeds and skins. I’m sure the smaller jar is much more conducive for that function hence that is the only way that feature will work. There are 3 speeds and a “pulse” button for basic blending. The controls are simple, easy to read, and not confusing to use. Only the Auto IQ buttons give you totally automatic control where you can set it and walk away. The unit is powerful! It sounds strong and it does make some noise mixing and pulverizing ice. The base unit has suctions cups on the bottom, and it will stick to your countertop. Good to stabilize the unit, but bad if you want to move it a few inches away as you will need to pull it off the countertop. The blender works well and is powerful. It is tall and just fits between your counter and the upper cabinets. If your upper cabinets are low, it may not fit with the tall jar installed. I like the easy to read controls. I miss the ability to add ingredients or ice through the lid. The locking lid can be confusing and must be installed and locked correctly, if your dexterity is poor you may have some trouble. Also when running the blender I noticed an odor like an electrical smell from the motor. Nothing serious, but something I haven't noticed from my other blenders. I found the easiest way to clean the jar is to add some warm water and a drop or two of dish soap. Then start a auto cycle. It will do a great job of cleaning the jar, then just rinse and dry. All in all this is a good blender and smoothie maker. I would recommend it to a friend but just can’t give it a full 5 stars, I give it 4 stars.

The best blender I have ever had. Worth every penny spent on it.

I’ve had this blender for quite some time now. It’s the best kitchen investment that I could have made. I’ve been able to make all my smoothies super fast with this blender. It’s so convenient to have the auto iq feature. Because I know it will make it right. And I love the individual cups that I can take on the go as well. If you’re just thinking about making the purchase just go ahead and do it! You won’t regret it.

We love this Ninja!! I make smoothies with just a 1/4 cup of any juice, pineapple, apple, peach and add 1 cup frozen strawberries, 1 cup frozen blueberries, and watermelon and the grandkids love it so much I bought them one for Christmas. They get plenty of vitamins and fiber. It’s fun to make for the hot summers as well.

Very happy with the Ninja blender. Use it almost every day. Strong blender.

I've used it to blend everything. Shakes, protein shakes, smoothies, salsa, and many many more. It's everything I wanted in my blender! Here's to being able to make your own food at home too!
