I'm giving the Ninja Kitchen system such a low rating as it is not able to do the main purpose for which I bought it. I'm a fairly healthy eating person and I love making protein smoothies after a workout. I've been wanting to add some leafy vegetables to those smoothies but my normal $30 blender just turns it into something resembling salsa consistency. I'm willing to splurge on kitchen appliances but that $600 blender seemed absurd to me. Surely I can find something for less that would work! After hearing so many other raves about Ninja products I decided this was the way to go for me. I even discussed with numerous people who own one (my friend uses hers to make baby food and it works great). I did see some reviews stating it doesn't pulverize things but I decide those reviews were a fluke. So I started watching sales and on black Friday I bought myself the Ninja Kitchen System. I was so excited to receive it! The night it came I immediately got it out and made my son and I slushies. For this purpose it is wonderful!! Ice literally becomes snow! The next morning however I broke out the spinach for what I hoped would be an awesome smoothie. My spinach was NOT pulverized and instead simply torn into tiny pieces, leaving my smoothie not very smooth. I thought maybe I didn't do it right so that night I read the manual front to back and read around online on how to get it to pulverize. Everything said to push #3 and let it blend until the desired consistency. Next morning I tried again. Still just tiny pieces. Since then I've also tried kale and lettuce. I've tried adding more water. I've tried adding ice. I've tried making smaller batches. I've tried larger batches. I've added bananas to help emulsify. No matter what I've tried IT WILL NOT PULVERIZE LEAFY VEGETABLES!!! Which was the only reason I bought this thing. I'll be saving my money and purchasing the Vitamix. I'm undecided on whether I will keep this at all. Probably not. I liked that it was also a food processor but I can buy one of those for half the price. Also for mixing cookie dough or such things, I own a Kitchenaid mixer so that doesn't benefit me at all. Now that I'm writing this out I can't really think of a reason I would keep this.... Now if you think green smoothies are disgusting, and you have no need to go pulverizing vegetables then this is probably the way to go. Also maybe you don't own a mixer or a food processor. How convenient that this does all of that.... To its credit It is quite powerful. All the pieces seem sturdy. And the suction cup on the base is a nice touch. Otherwise if you want a Vitamix, I'd suggest saving your money like me, and go buy a Vitamix.
