Nutri Ninja Blender with FreshVac Technology, 1100-Watt Auto-iQ Base, 2 Manual Speeds, and (2) Single-Serve FreshVac Cups with Lids (BL580), Dark Gray

I don’t know why Ninja would stop making this vacuum juicer. I have been juicing with a Vitamix for years and have always been concerned with oxidation- which is why I never juice the night before and always drink straight away. Now I am able to make two drinks and save one for tomorrow without losing nutritional value or texture! And it isn’t $599!!The machine works great. Mine was definitely new- not a renewed item. NOTE: you don’t have to use 6 AA batteries. They sell an adapter for it but I got a universal/adjustable AC adapter for $20 and it is fantastic. I too was concerned with performance when batteries are running lower.I love the ‘smoothie’ button. It does a a few long pulses for you to better gather the ingredients. I no longer have to babysit the blend. Incredible!! I love everything about this blender.Of course, keep the little seal clean and dry for max vacuum. And read the fricken directions!!Easy to use and clean. Noise wasn’t bad at all in my opinion. People are generally more likely to complain than give kudos.As far as the review being gimmicky- I have not tried one cup with and one without vacuum. But the juice I refrigerate for the next day does not separate like the ones I have made with the vitamix did. I too always use beets- as well as spinach, protein powder, various adaptogens, blueberries & raspberries, and ice.I like to make one for now and one for tomorrow. The one for tomorrow, I will vacuum both before and after blending because you can’t pull the air out of the ice. You can visualize the air being pulled all through the layers of liquid. I run a THIRD vacuum on the refrigerated cup before I go to bed. It’s so quick and easy to do! *Somehow, there is air either seeping in or producing inside. Overall, there is far less oxidation with this system than without so I am thrilled with it.

I spent a lot of time looking at reviews when shopping for a blender and ultimately chose this one despite some of the negative comments about the fresh vac technology. I hope this review is helpful to others.Yes...the blender is noisy but ALL BLENDERS ARE NOISY. If you don’t want a noisy blender, don’t get a blender. This is no more noisy than any other blender I’ve owned.You have to pay attention to fill lines. If you want it to blend properly, don’t fill past the line. This also impacts the vacuum technology. Some of the reviewers complained about it sucking up milk...that’s because they overfilled it. I haven’t had any problems once I discovered this. I also made pina coladas in it using the vacuum and, where they always got foamy before, I didn’t have that issue so it does something right. I don’t use it all the time but it does work.I will say that it is easier to wash this in the dishwasher than by hand. That’s my only complaint if you can call it that.Overall, this is a great unit at a great price and I’m glad I bought it. I make smoothies for my girlfriend and myself every morning before work and just screw on the flip top lids and off we go. Awesome!Buy with confidence and ignore reviewers suffering from user error.

This is my first ever blender purchase, and I've got to say - I am very impressed. I grew up in a health nut family that used one of those loud Vitamix blenders that get all hot if you use them for too long, but have great blending power. This Nutri Ninja is exactly what we needed. We're not typically grinding anything too hard though, just making smoothies with frozen fruit. I have had to run the blend cycle a couple times before just to get all the chunks blended, but it's not a big deal and is most likely due to me loading it too full. Plus, we even had to do that with the Vitamix, so not a big deal for any blender. When we put fresh berries inside I notice it doesn't blend all the seeds, but I personally don't mind that. Didn't bother using the freshvac, as it seemed kinda gimmicky. I like that it comes with two smoothie cups and lids, and the cup itself is relatively easy to clean, but beware that gunk can get trapped under the little plastic vacuum seal portion at the bottom, so take it out to clean the cup fully. Overall, very happy with this blender, and would recommend to anyone who loves quick smoothies.

I bought this blender to go to and from work with my green smoothies in the morning and it's been pretty awesome! I have to say that one of the cups that came with it leaked almost from day 1. I was ...perturbed. There's NOTHING like getting to work to find green smoothie all over everything in your purse! It's like 20 degrees out here sue me for putting it in my purse, it was way to cold to hold a frozen smoothie all the way to work on the metro. I don't like to "eat" on the train, so I finish whatever I didn't eat in the car at work... The little green rubber seal at the bottom appeared to be damaged in some way. I assumed (wrongly) that the black plastic connection could hold the cup closed. So, for several weeks, I was down to one cup, which wouldn't be that bad except that one is used to blend baby food and should be home with the nanny. I quit smoothies cold turkey. Then, I remembered Amazon's phenomenal custome rservice and went to get help with this order. Their information page directed me to call Ninja, which was immediately disappointing BUT, I got Ninja on the phone after a very short wait and was immediately told that the product was in warranty and they would mail me another one. So, three weeks of angst when I could've just called (or returned the whole kit and caboodle to Amazon). Really, I should give it a 5, but the blade is prodigiously hard to get cleaned ;)Great blender. It gets my smoothies and the baby's food reasonably textureless, which is a big deal for me. I've been using a BlendTec for 10 years (which i love), but this is giving it an ENTIRE run for its money on the smoothies! We will see how long the motor lasts.
