I am not an expert of writing blender reviews as this is my first blender, ever. I haven't played much with it beside making smoothies every other day, which included kale, spinach, ginger, spinach mix, banana, frozen berries and protein powder. Freshvac - Nice feature but sometimes it takes more than a minute (when using a pitcher), which is not a big deal. Is it worth it? Not a must have but I am happy with it as color is rich but not sure if taste is different when comparing with smoothie which was made without using freshvac. 2 glasses- they come with it which are great and convenient for someone who is making only small 1-2 glasses of smoothie instead of using a pitcher. Functionality - out of 20 times so far, I had seen once when some greeny leafs weren't fully blended (maybe due to overfilling the bottle). Satisfied so far!!

We love our Ninja blender. We use it every morning to make our healthy smoothy. And it is multi functions touch function is very amazing and easy to clean.

This Ninja Duo Smart Screen blender makes Smoothies, Purees or just about anything you could possibly think a blender capable of doing. It just does it better than you ever imagined a blender could do things. It includes a FreshVac system, which is truly unique and helps with nutrient and vitamin extraction during the blending process, by removing the air in the Pitcher or Single Serve cups. Simply place the battery operated FreshVac Pump on either the included Pitcher or Cups and touch a button. The FreshVac removes the oxygen in the canister, then just blend away and you'll be amazed at how effective and better looking your blended concoction will be. It's not just better looking, it's smoother, with less foam and it really does taste better than the smoothies I made with my NutriNinja (which this replaces). According to the manufacturer, the blade system better extracts vitamins and nutrients from fruits and vegetables. It comes really nicely packaged, with 2 20 oz. single serve FreshVac cups with lids, a 72 oz. FreshVac pitcher, 6 AA batteries (for the FreshVac Pump), the 1400 Peak Watt motor base, removable blade assembly and a recipe book. With Smart Screen Technology, at a touch of a setting on the screen, you get customized power and speed via 7 pre-set Auto-iQ programs to achieve the perfect result for the job with no guesswork. It's smart. It's effective. It just works! The feet on the blender are suction feet. This is great. With 1400 Watts of Peak power, you'll never have to worry about the blender walking around your counter top. All the parts are dishwasher safe. I've been a Ninja customer for a long time. Based on my personal experience, Ninja's are simply the best. They're versatile. They're well made. And they last and last. This new system is just a much more intelligent take on blending that will make my morning smoothies taste better and healthier. What more could one ask or hope for?

This blender is a substantial upgrade to standard blenders. First of all, it’s a Ninja system so it has a 1400-watt motor that can be used to blend anything. I’ve had a couple of Ninja systems and can’t say enough about having the more powerful motor than standard consumer blenders. What makes this system so unique is the Freshvac technology that’s employed to make smoothies have less foam and a richer taste. The system consists of the 72-ounce blender pitcher, 2-20 ounce single serve Freshvac cups and the Freshvac pump. A couple of things to note about this system: the main pitcher and single serve cups are made out of heavy-duty plastic and the pump requires 4AA batteries in order to operate it. These are ‘cons’ in my opinion because if you want to blend hot liquids, you need to wait for them to cool down before blending them. I would be happy if at least the main 72-ounce pitcher was made from glass. The Freshvac pump needing batteries is more of an inconvenience to me. I would rather see it be a recharge able device than one that uses consumable batteries. You do have the option of using an optional AC power cord, but I’d rather it be a cordless, rechargeable device. Aside from those small issues with the design, I think the Ninja Duo Blender does a great job with mixing and blending drinks, purees, and anything else you throw at it. The Freshvac technology was a new adventure for me as I’d never even heard of it before I got this system. That said, I definitely can tell a difference with the finished product when I remove the oxygen from a smoothie versus when I leave it in. The texture was much smoother than when you don’t use the vacuum. This is a big win for me as texture is something that really bothers me — especially when it comes to blended drinks. Even though this is a sophisticated system with lots of parts (at least more than just a single blender), the Ninja Duo is well worth the time it takes to learn the system. I can recommend this system to anyone who likes to have blended drinks it can really enhance your experience. It’s easy to use with the pre-programmed modes and clean up is a breeze since the control panel is sealed and waterproof.

There is more than meets the eye with this blender. First of all, this blender has a larger than normal reservoir. It can hold 72 ounces, my previous blender holds significantly less than that. Another feature that this blender has that my older blender does not is the FreshVac. This feature acts as a food savor/oxygen remover while the load is being blended. At first i thought it was a bit of a stretch, which i must admit at face value it is, but never the less, it does improve the texture and flavor of whatever is being blended to perfection. All in all this is a good blender, some small tweaks could make it a top notch blender, but overall a very powerful and efficient blender.
