Posted .Hi Mishra,
Thank you for sharing your feedback about the Ninja Professional Plus Blender Duo. We’re sorry to hear about your concerns with mold development, even after limited use. This is certainly not the experience we want for our customers, and we’d like to help.
Mold can develop if the blender components, especially the blade assembly and seals, are not thoroughly cleaned and dried after each use. We recommend disassembling all removable parts and cleaning them with warm, soapy water. Ensure all components are completely dry before reassembling to prevent moisture buildup.
If you’ve already taken these steps and are still experiencing issues, please don’t hesitate to reach out to our Customer Service team at 1-800-365-0135. We can provide additional cleaning tips or explore warranty options if needed.

Will Crush Through Anything
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.(Note that this is a blender mostly for drinks not food) Let me start by saying this blender will crush anything you put in it. Big chunks of ice?? no problem, protein powder?? no more lumps, big pieces of fruit?? easy. The big reasons this blender is able to do all this, is because of the 3 blades inside and the 1400 watts that power those blades. There is really no complex settings on this blender, there are 7 modes and 3 of them are preset to smoothies, ice crushing, and extract. Inside the box you get your blender the big jar and 2 cups with lids and the blades for the cups. The only thing i wish this blender would come with, is a glass jar since some fruits/veggies tend to leave strong smells or leave stains in plastic. Honestly if you are looking for a blender to make good smoothies/juices, I would recommend you this blender

Great Everyday Blender
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Ninja Professional Plus Blender DUO is super powerful and really easy to use. It crushes ice and frozen fruit with no problem, and the Auto-IQ presets make smoothies basically foolproof. I also love that it comes with to-go cups for quick shakes. Cleanup is simple, too. Overall, a great everyday blender that feels solid and worth the price.

Convenient and flexible blender!
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This Ninja Professional Plus Blender Duo is a really nice machine. I love that this blender comes with both a large pitcher and two smaller blending cups. Often I just need to make a single cup for myself, so it is really nice being able to use the smaller blending cups in that circumstance. They are a little easier to clean than the larger blending pitcher. When blending for multiple people, it is great to still have the larger pitcher as an option. When blending with the smaller blending cups, I would strongly advise that you rinse out the blade part right away after using. I had another Ninja single serve blender in the past, and rinsing right away can help to keep the rubber ring in that piece clean and just makes cleaning quicker and easier overall. It is also a good idea to quickly rinse out the larger pitcher right after blending as well. This machine performed really well during my usage. The small blending cups worked really well for blending for one person, and the pitcher does a great job with larger batches and with blending frozen ingredients. When blending, this runs for a bit and then pauses to ensure that unblended pieces fall down to the blade and get blended fully. Once the drink is blended in one of the single serve cups, you can take off the blade and use one of the provided lids with a spout which is really nice for taking blended drinks on the go. The larger pitcher has a spout that makes it easy to pour out what you have blended without having to take the lid off. Cleanup is pretty easy on both the small blending cups and the pitcher. The blender cups in particular are really easy to wash out which makes it very convenient to use them for single serve drinks on a regular basis. The larger pitcher makes blending large amounts easy and really does a good job at blending things such as ice and frozen fruits. It doesn’t do quite as good at blending leafy greens and I think this is due to the design of the blades which is different from that in the single serve cups. With this machine, you have the flexibility to choose what works best. So for things like crushing ice or heavily frozen smoothies, the big pitcher should perform really well. And with drinks that contain many different things including greens and such, the single serve blade and cups work great. I’m not sure if the blades and such for this blender are dishwasher safe, but when handwashing, the big pitcher is more work to clean. It has more to clean as far as blades go, and unfortunately Ninja did not include any sort of brush to clean them. It would have really helped if Ninja had included a brush to help with cleaning the blades both on the big pitcher and the single serve blade. That being said, the ability to easily remove the blade from the big pitcher does make cleanup a lot easier. You can take the blade out of the pitcher entirely so you can clean both pieces separately and you can get all the way down into the pitcher without having to worry about getting cut by the blade. This blender also has suction cups on the bottom which help to hold it in place wherever you are using it, and it also has a piece that sticks out in the back which makes it easy to wrap the power cord around for storage. This blender feels like it is a solid piece of equipment and also has a great design that is aesthetically pleasing. Overall, I am happy with this product and would recommend it to others. The flexibility that it offers in blending is great, it worked well throughout my testing, and it is easy to clean up.

NINJA - QUALITY BLENDER WITH GREAT VALUE
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this to replace a Ninja blender I purchased about four years ago and the motor went bad. I'm very happy with this replacement. Then good: It’s a great price at around $100 as of mid-May. It’s compact size allows it to move in and out from under cabinets. I use it nearly every day and it's comforting to know I can make a completely blended smoothie by just throw everything in and use the auto-IQ feature. At 1400 watts, the power is more than sufficient to handle most needs. The small portion cups are a perfect to-go size and the top makes it easy to transition from blender to truck. Suction cups on the bottom makes it easy to set and come back when it’s done without concern of it shaking itself off the counter. The bad: There is no timer for the IQ setting. The power cable management on the back could be better as the plug doesn’t sit firmly in it’s slot and it flops around behind the blender. I don’t like how the top doesn’t close down when not attached. Makes stacking in the dishwasher more complicated than it needs to be. The easy-pour lid may look great on paper but if you make a thick drink, the opening isn’t large enough so it’ll glob out and drip down the outside. It’s quieter than many other blenders out there but still makes my wife jump out of bed when I turn it on after returning from my morning run. Overall, this is an outstanding replacement for what was previously the best blender I've ever had. I’ve always been a fan of Ninja and would have no qualms about purchasing another next time.

Loudly petfect
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My Ninja blender is powerful & makes excellent smoothies everytime. I especially like the option that blends the smoothie with several blends interspersed with pauses. It completes the job & turns off. Every time the smoothie is perfect. The only downside is its loudness. But thankfully, it makes a quick smoothie!

Powerful and fast
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This Ninja Pro Plus Blender Duo is amazing and powerful. The three tiered blade system ensures even and quick blending or chopping. Making salsa is ridiculously quick. Making smoothies is super quick and easy. No chunks. Ice does not stand a chance against this powerful motor. In addition, the included single serving cups are great if you only want to make enough smoothie for yourself. While using this product, you can tell that Ninja did not skimp on the quality of the motor and it appears that this blender will last for a long time to come. The base uses suction cups to stick to the counter reducing vibration and noise. If you don't want to blow $500 on the industry standard mixer, this will be a best bang for your buck and and should last you a long time. Its one of the few products that Shark has gotten right.

Powerful and Flexible, not Ninja Stealthy
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.With a name like Ninja, expectations are high. Who hasn't talked about this bold brand's ruthlessly powerful blenders and food processors? I've used versions of a well-known competitor's smoothie-focused products, as well as long-standing brands' blenders. It was time for me to move to a single appliance as my COVID cooking game has been raised considerably. The Ninja Professional Plus Blender DUO with Auto-iQ (a mouthful, no pun intended) seemed like a good upgrade. I've learned you only need a few settings to perform just about any blending/processing endeavor in the kitchen. No need to complicate! That said, they send a bunch of essential parts and accessories. The "Total Crushing Blades" are out of some sci-fi novel, but they live up to their name. Ice of all shapes and sizes- handled. Nuts? Handled. Root vegetables? Handled (and make a pretty smooth juice too!). The Extractor Blades work like a conventional blender. No surprise there. You're also given a large pitcher with a lid that ensures safety and prevents messes, to 24" blending cups and lids - think "running out the door with my smoothie" or perfect for diving up soups and margaritas. Operation is easy. The box includes a Quick Start Guide and full Owner's Manual. Page 2 of the Guide explains the Auto-IQ features. It's kinda old-school but with a flush interface and smarter than you ;) In addition to the on/off, there are Smoothie, Ice Crush and "Single Serve Extraction" settings that know the speed and timing necessary for your goals. Additionally there are the standard manual speed (low-medium and high) and pulse settings. I really couldn't find a reason to overrule the pre-sets, other than making soup. Final pros- Suction cups on the base for stability The blending containers and tops lock-down for safety and cleanliness. Con? It's EXTREMELY LOUD! There will be no surprise blending going on in the house. Overall, this could be a lifetime appliance. It's very powerful, with plenty of flexibility.

Excellent upgrade full of nice features
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I've had a ninja for about 10 years now. Still works fantastic. But because of its age, i couldn't adapt the new single serving containers for shakes/smoothies. One of the simplest and subtle improvements is the suction cups for feet. i don't have to worry about holding the base while running, which is real convenient when you're multitasking. I can hit a Auto IQ program for a smoothie and walk away and it'll stay stuck to the counter top and mix while i'm cooking other stuff. its the little things i appreciate I haven't used all programs yet, but so far so good, i can dump my fruit and ice and whatnot in, hit smoothie and continue cooking the rest of my meal. For those that don't care for that feature, the manual controls work just fine as expected. Still just as powerful as Ninja's always been. The pitcher seems to be thicker than previous models and there's better rubber seals between the lid and pitcher and even the spout cap to the lid. Seems much more durable clean up is just as easy, everything comes apart nicely and there's no tight nooks or crevices that are hard to get to, which is great so there's less risk of uncleaned food going bad and being caked on

Amazing Blender
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This is an amazing blender, it is perfect for smoothies and can blend frozen fruit, ice and other ingredients easily. The pre set functions work well, and I am impressed by the quality, efficiency, and effectiveness of the product. One of the critiques I would have is that it is a bit loud, but that is normal for blending units. The extra smoothie drinking attachments make this very convenient for quick smoothie usage. This is a genuinely great product.

Blend your own smoothies
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been a happy Ninja owner over the years. This is actually the third ninja blender I own. The first one served me well for a couple of years and I still have and own a smaller single serve blender by Ninja. Anywho, this new Ninja Pro Blender with Auto IQ doesn’t disappoint. I use mine mainly for home made smoothies. It pulverizes frozen fruits and vegetables and makes very nice thick and flavorful smoothies. The two single serve cups included are great for on the go drinks and very easy to clean. I use the large pitcher when I need to process food or make multiple servings to share. It’s great for margarita parties! The large pitcher is very strong and the blade is locked securely in place by the lid. Be sure to keep the lid on and use the spout to pour out your drinks or blend. The blade will fall out if you remove the lid to pour. The blades are intimidating lol but very simple to clean outside of the blender. I don’t have a dishwashing machine so It’s a very convenient feature for me. The Auto IQ presets and multiple speed settings make blending quick and easy. The pitcher and cups lock into the base so you can start the blender with the preset of your choice and go on about your morning routine. Would I recommend this blender? For sure! Especially if you enjoy making your own frozen drinks and smoothies. It can blend just about anything you throw at it with ease and is easy to clean up after. Pros: Pitcher, cups and blades lock securely into place Easy preset buttons and multiple speed settings Very fast and powerful blades Excellent value Easy to clean

My 2nd Ninja in 12 years! They're The Best!
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought the best Ninja blender pack duo you could buy 10 years ago, and on the box, it says will last 10 years. Let me tell you, we used our blender almost every day for the past 10 years and it did indeed stand up to it's potential. So, I bought this blender to replace my other blender from 10 years ago, and given that it doesn't have an LCD screen, which I'm fine with, it is intuitive! Its powerful performance is a total game-changer in the kitchen and the Autu-IQ does a phenomenal job. I am a big-time smoothie drinker, and this blender for the price is perfect! It crushes ice and frozen fruit like it’s nothing. The Auto-iQ technology takes the guesswork out of blending — you just press a button, and it automatically adjusts blending, pulsing, and pausing to give perfect results every time. The full-sized pitcher is perfect for making large batches, and the single-serve cups with to-go lids are ideal for busy mornings. Cleanup is super easy too, since all the parts are dishwasher safe. It feels sturdy, looks great on the countertop, and outperforms blenders that cost twice as much. If you’re serious about blending and want something that delivers power, precision, and convenience — this is the one. Highly recommend!

Ninja Never Disappoints
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This blender/personal size blender is amazing. You can add your ingredients to the pitcher/cup and blend the most fabulous smoothies. The ice crushes nicely and everything mixes well. It is very easy to use. The lock features on the machine and the lid are a nice addition. It is very nice to have the personal size and make a single size as easily as the family size pitcher. I highly recommend this blender.

A Blender I Actually Use Every Day!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I usually get bored quickly with kitchen gadgets, but not with this one. The Ninja Professional Plus Blender DUO with Auto-IQ has become part of my daily routine — smoothies in the morning and frozen margaritas in the evening! Yes, it's made entirely of plastic, but that hasn’t been a downside at all. In fact, it’s surprisingly durable.

Not only is it functional and powerful, but it also looks great on the counter. For someone who usually loses interest in kitchen appliances fast, this one really stands out. I’m 100% satisfied and still enjoy using it every single day.
