Ninja BN751 Professional Plus DUO Blender Review and Comparison

When it comes to upgrading a trusty blender, I like to take the time to thoroughly research top-rated models. After putting in countless hours blending smoothies, soups, and more over the past few years, it was time for an appliance with more power and versatility.

That’s why I decided to closely examine the Ninja BN751 Professional Plus DUO Blender. As someone who relies on their machine for daily meal prep as well as entertaining friends and family, I know everyone needs a workhorse that can handle any recipe with ease.

After diving into online reviews and comparing other different models, this blender seemed to check all the boxes for my readers’ needs. With its sturdy build quality, multiple jar options, and powerful motor, it appeared capable of taking my blending to the next level without breaking the bank.

In this review, I’ll share my first-hand experience testing out the BN751 over several weeks of regular use in my kitchen. From smoothie-making to sauces and more, we’ll see how it stacks up against my previous blender. My hope is this overview helps anyone else seeking an affordable yet powerful machine to add to their arsenal.

Overall Look and Design Testing

At first glance, this appliance cuts an imposing figure on the countertop with its above-average height of just over 17 inches. However, once you start blending, that extra stature proves handy for fitting larger food containers inside with ample clearance.

The under-8-inch width allows it to sit comfortably alongside other kitchen tools too without crowding workspaces. And while its depth pushes close to 9 inches, that still leaves room to open nearby cabinets fully.

At only around 8 pounds, the unit feels reasonably lightweight considering its full-size capabilities. Transporting or storing different components like the removable pitcher is simple enough for one person too.

Overall, while its dimensions make cabinet storage impractical, the sleek design nestles neatly on most countertops without dominating the entire surface. It’s easy portability also provides options to tuck parts away as needed.

This model is similar to Ninja BN701 Professional Plus Blender since the motors have the same options.

Jar Material & Capacity Testing

The first thing that drew me in was its solid construction. With a substantial weight and sturdy plastic housing, it’s clear this machine is built to last through years of regular use. While not the sleekest design, I appreciate function over flash. 

Upon testing it out, I was impressed by the power and performance it delivers. The sharp blades make light work of any ingredients, from tough nuts to frozen fruit. Within minutes you can get the smoothest almond butter and creamiest green smoothies. The multiple speed settings give me full control over textures too. 

With a generous 72oz pitcher and convenient 24oz travel jar, this blender caters to any meal prep needs. I love being able to make large batches for the week or just a single serving for busy mornings. Both vessels lock securely onto the base and everything is dishwasher safe, which is a huge plus for someone as busy as me. 

Subtle touches like the non-slip base, backlit controls, and foolproof lids help take prep to the next level. Whether I’m blending soups or baking smoothies into my routine, this blender delivers consistent, mess-free results time and time again. 

You may see the jars of this model in the above picture that is very clear.

LID Testing

I was happy to find that the main pitcher’s lid is really easy to put on and remove from the jar. The way it works is that it locks into place using the handle, which is a nice and secure system. One thing to note, though, is that it’s not a 2-part lid, which means it doesn’t have a removable center piece that would allow you to pour in more ingredients without taking off the entire lid. This might be a bit of a drawback for some people, but it’s not a huge deal.

However, there is a convenient feature that makes up for it. On one corner of the lid, there’s a spout that you can open to pour from the pitcher without having to remove the lid entirely. This is really handy when you’re trying to pour a smoothie or soup into a cup or bowl.

In addition to the main pitcher’s lid, there’s also a to-go lid that comes with the personal jar. This is a great feature for anyone who likes to take their blended drinks on the go. The to-go lid is designed to be secure and leak-proof, so you can toss it in your bag or take it in the car without worrying about making a mess.

Motor Built Quality Testing

When it comes to the motor of the Ninja BN751 Professional Plus DUO Blender, one thing that really stands out is its great build quality. The base and transmission of the motor are made of plastic, which might not sound like the most durable material, but trust me, it feels sturdy and reliable. In fact, it’s similar in quality to the Ninja Professional Bn801 Plus Kitchen System with Auto-iQ, which is a high-end blender.

The control panel of the blender is also worth mentioning. The buttons are nice and clicky, which makes it easy to navigate the different settings and features. And when you turn it on, the display is bright and easy to read, which is great for those early morning smoothie sessions.

But what about the personal jar and blade assembly? Well, I’m happy to report that they also feel well-made and sturdy. The blades are sharp and durable, and the jar is easy to clean and maintain. And let’s not forget about the suction cups under the blender’s motor base. These little guys do a great job of keeping the blender from moving around on your counter, which is especially important if you’re blending hot soups or frozen ingredients.

Blades Quality & Speed

The Ninja blender is equipped with six sharp blades that are designed to tackle even the toughest ingredients. The blades are precisely engineered to provide maximum efficiency, ensuring that your smoothies, soups, and other blended creations turn out smooth and consistent.

One of the most convenient features of this power machine is that the blades are removable. This makes cleaning a breeze, as you can simply pop the blades out and wash them in the dishwasher or by hand. 

You can just imagine how easy it will be to blend your favorite ingredients, and then simply wash the blades and pitcher in the dishwasher. It’s a game-changer for anyone who loves to blend.

The blades and pitcher are both safe to put in the dishwasher, which means you can blend to your heart’s content and then simply load the dirty parts into the dishwasher and it’ll clean all. This is especially convenient for people who blend frequently, as it saves so much time and effort.

The main pitcher’s blades are stacked in a unique design that allows for maximum blending power. This means that the blades can tackle even the toughest ingredients, like frozen fruit or thick vegetables, with ease. With the second blade assembly included, you can attach it to the personal jar like a lid, making it easy to blend on the go. 

The blender’s powerful 1,200-watt motor drives the blades to incredible speeds. With a minimum speed of 3,900 RPM and a maximum speed of 4,900 RPM, this blender can handle even the toughest ingredients with ease. Whether you’re blending frozen fruits or thick vegetables, this blender has the power to get the job done. 

One thing to keep in mind is that the speed adjustment isn’t super fine-tuned. While you can still adjust the speed to suit your needs, you won’t be able to make tiny adjustments to the speed or start at a low speed and gradually ramp up to a high. This means that you may need to experiment with different speeds to find the one that works best for your specific blending needs. However, for most blending tasks, the speed range provided should be more than sufficient.

Performance

Nut Butter

After testing out different recipes, I found this blender really shines when it comes to making homemade nut butter. Thanks to those powerful blades, ingredients like almonds and cashews are transformed into an ultra-smooth, nearly liquefied consistency.

The texture is really where this machine excels – nut butter comes out perfectly creamy and spreadable. However, the process does require some patience. Blending nuts takes a fair amount of time as the motor works overtime to fully pulverize them.

You’ll likely need to stop periodically to scrape down the jar with a spatula too. All those tiny nut pieces have a tendency to stick to the sides until thoroughly blended. It’s a bit tedious compared to some models with auto-scraping features.

Crushing Ice 

When it comes to making crushed or snow-like ice, this blender shines. As someone who enjoys blended frozen drinks on hot days, I was impressed by how easily it pulverizes ice cubes.

By using short pulses on the blender’s manual setting, those powerful blades make quick work of transforming cubes into an ultra-fine, uniform texture that’s almost powder-like. It’s perfect for concocting frosty cocktails or smoothies with an icy kick.

No more partially crushed cubes or larger chunks mixed in. The BN751 methodically breaks everything down into tiny, fluffy ice particles. Cleaning is also a breeze since no larger pieces get stuck in crevices.

If you regularly entertain or love DIY slushies, it’s clear this blender was built for the task. A few quick pulses are all it takes to stock your freezer with “snow” for blending up cold treats.

Smoothies 

While this blender handles many tasks well, fibrous greens seem to give it more trouble. When making larger smoothies with hearty kale or spinach in the full-size pitcher, there tend to be noticeable flecks left over no matter how long it runs. 

However, where this machine comes into its own is for single servings. Using the personal-sized blending jar, even stringy greens like kale are thoroughly pulverized into a silky-smooth texture. It takes the fibers to task with ease.

Compared to blitzing greens in a full batch, the compact jar allows for more targeted blending. Every nook and cranny is saturated, leaving nothing unblended. A kale and banana smoothie takes on a lovely emerald hue without any stubborn chunks ruining the consistency.

A few minutes is all it takes to achieve a luxuriously smooth texture that slips down with ease. While some larger capacity blenders may be faster, this little jar delivers impressive results for its compact size. Perfect for busy mornings or meal prep on the go.

How to Use Ninja BN751 Professional Plus DUO Blender

This blender keeps things simple with its control layout. There’s a single red power button that acts as an on/off toggle – you have to press this to get the motor running. Speed options are limited to three preset levels that can be selected with dedicated buttons.

While it lacks a variable speed dial, presets are generally enough to handle most blending tasks. You’ve also got a pulse function for more manual control. Simply press and release the pulse button to blend in bursts.

As for automated programs, there’s a “Smoothie” cycle optimized for blending ingredients in the full-size pitcher. This runs for about a minute, which seems like plenty of time to puree smoothie mixtures nicely.

An “Extract” setting is available when using the personal blending jar. This one-minute program is tailored for tougher items like leafy greens that require extra blending power to break down fully.

Noise Level

When it comes to powerful appliances like full-sized blenders, noise can often be a concern. Many tend to be quite loud while pulverizing ingredients at their top speeds. However, from my experience testing the Ninja BN751, I found it to be surprisingly quiet for the performance it provides.

According to the specs, it clocks in at around 88.8 decibels at maximum power. To put that into context, a normal conversation is around 60 decibels. So while not completely silent, the BN751 operates at a volume comparable to average talking voices.

Compared to other heavy-duty blenders I’ve tested, like the Ninja Foodi and KitchenAid models, this one seems to keep noise levels more reasonable. Those tend to reach the 90+ decibel range and can really fill a kitchen. The BN751 is noticeably quieter and less likely to disrupt conversations in adjacent rooms.

How to Clean Ninja BN751 Professional Plus DUO Blender

One aspect I’ve noticed with this blender is that cleaning can sometimes be a bit tricky. While I appreciate how the blade assembly detaches from the jar base, those sharp blades do require careful handling. Scrubbing by hand risks potential nicks or cuts, so extra caution is needed. 

It also seems like food bits have a tendency to get lodged in inaccessible areas. There’s a narrow groove where the blade stack inserts into the pitcher that is difficult to reach with brushes. No matter how thoroughly I rinse right after use, tiny remnants will linger in that hard-to-clean crevice. 

Over time, I’ve found these stubborn spots are what cause messes to build up and dried-on gunk to form. Even putting the whole jar in the dishwasher doesn’t always dislodge everything trapped in that tight space. It takes some muscle and an old toothbrush to scrub it clean. 

While the blender performs well for its price, cleaning thoroughly definitely requires more effort compared to some other models I’ve checked. The tight design makes complete rinsing tricky. Small design tweaks could help make post-blend clean-up a bit less of a chore. 

Comparison with other Models

Ninja BN751 Professional Plus DUO Blender Vs BLACK+DECKER BL1400DG-P

Let’s start by taking a closer look at the Ninja. Right away you notice its sturdy, heavy-duty construction. The thick glass jars and heavy-duty motor base mean this machine is built to last. I’ve had mine for over two years now with no signs of slowing down. When it comes to crushing ice, nothing beats the Ninja. Those sharp blades make light work of cubes, transforming them into snow in just seconds. This is perfect if you enjoy frozen cocktails on hot summer days or slushie treats.

However, I have found the Ninja’s intense blades can sometimes have trouble fully pureeing thicker, fibrous ingredients like kale, carrots, or ginger. The small holes in the lid allow just enough space for stringy bits to get caught. This isn’t ideal if you want your smoothies to have a silky-smooth texture. The Black+Decker, on the other hand, excels at this task with its gentler blending motion. 

While slightly less powerful than the Ninja, the Black+Decker’s smoothie-focused design means it better tackles pulverizing things like bananas, berries, and leafy greens into a homogenous mixture. I barely have to stop and scrape down the sides. Its wider feeding chute also means less pre-chopping for busy mornings. The trade-off is that, like most standard blenders, it takes a bit longer to crush a giant batch of ice due to less intense blades. You’ll likely end up with some larger chunks mixed in.

Ninja BN751 vs Ninja TB301 Blender

These blenders feature large 72 oz jars perfect for big batches, as well as smaller portable jars for on-the-go sipping.

The Ninja TB301 blender is equipped with a 1200-watt motor. Despite the same wattage motor, it allows the detect pro to thoroughly pulverize even the toughest ingredients. Things like kale, spinach, and carrot tops that can sometimes get stuck in weaker blenders simply don’t stand a chance against the TB301’s sharp blades. 

I personally found this made a huge difference in the consistency of green smoothies. When checking Professional Plus, I’d often still find chunks of unblended greens floating around. But with the TB301, everything is blended to an ultra-silky-smooth texture from the first pulse. The nutrients are fully extracted, making my smoothies much more enjoyable to drink.

Another area where the TB301 excels is convenience features. I appreciate the programmable settings that let me choose from pre-programmed routines like “Smoothie,” “Frozen Drink” and more with the press of a button. No more guessing how long to blend. It also includes a handy digital timer so I can start the blender and walk away without worrying about over-blending my drinks.

That said, the BN751 isn’t without merits either. As someone who does a lot of blending, I appreciate its rugged construction. The heavy-duty motor base and thick glass jars feel like they could withstand daily use for many years to come. I also found it runs a bit quieter during operation compared to the louder TB301. This may be preferable if noise is a concern. 

Ninja BN751 vs Ninja Foodi SS201 Blender

The BN751 DUO Blender immediately stands out with its convenient design. In addition to a large 72oz pitcher perfect for big batches, it also includes a single-serve 24oz jar just right for personal smoothies. Being able to make my morning drink with one touch is so handy on busy days.

Its sharp blades also whip through ingredients with ease. Things like leafy greens and carrots that can sometimes get stuck in weaker blenders are no match for the DUO. I find my green smoothies are fully pulverized into a silky-smooth texture every time. Cleaning up is also an easy way because its all parts make MPA plastic that makes it dishwasher-safe. The durable, heavy-duty construction means this workhorse will power through daily use for years.

Now onto the SS201 Foodi Blender. While its standard blending performance doesn’t quite rival the BN751, it truly shines thanks to the included dough blade. Being able to knead bread or pizza dough directly in the pitcher is so convenient – no extra mixing bowl is required. It also does a fantastic job grinding nuts into smooth butter without any chunks.

The Foodi is great for bakers and those who enjoy homemade nut butter. However, if smoothies or blended drinks are your primary focus, the DUO’s single-serve functionality and powerful blades give it the edge. 

Final Verdict

The Ninja BN751 Professional Plus DUO Blender has earned a permanent spot in most users’ kitchens. While not the flashiest or most expensive model out there, its powerful performance and thoughtful features have won it over after months of regular use.

Its sturdy build quality provides reassurance that it’s built to last, while the multiple jars accommodate any recipe. I appreciate how this workhorse tackles everything from smoothies to sauces with equal gusto. 

Subtle touches like the intuitive controls and secure lids also boost the user experience. Cleanup is a breeze, and having both large and small vessels means I can tailor batches to any crowd.
