The smoothies turned out good but the cups melted in the dishwasher! I do not mind handwashing but it said dishwasher safe. Now I’m stuck having to buy new cups.

I've owned 3 of these. I should have stopped buying them after the first one. I had to replace each one after 1 to 2 years. There are several reasons that I would not recommend these. The first is that the cups warp too easily. We wash them in the top rack of the dishwasher & invariably, it's only a matter of time before they warp anyway. The 2nd reason is that the black cutting/blending bottom piece eventually starts to make a horrible noise that sounds like the bearings are gone (if it even has bearings). After that starts, the unit is no longer usable. The 3rd reason is that Ninja keeps changing the design every time. We have to throw everything away from the previous machine since nothing is compatible with the new machine. That has been true for all 3 machines that we've owned. We bought a cheap Hamilton Beach blender for smoothies to replace the last Ninja. HB has a glass jar, so there's less plastic getting chopped up in the process, unlike the Ninja, which is entirely plastic other than the blade.

Initially, I absolutely loved this appliance in spite of cutting my fingers washing the blades. I thought this thing would last a century as the motor is very powerful. After a little over a year using it to make salsa probably once a month, the bottom of the chopping cup literally came apart. I have the other blender cup but figure it will be short lived too. I loved this appliance so much but quality is definitely a concern. The blade mechanism literally separated from the cup. I’m sure it hasn’t been used much at all. A new cup is very expensive and I figure that I’m better off replacing the food processor with a cuisinart than buy another cup. The blades and lid and most of the cup are intact. The bottom of the dicing mechanism separated from the rest. I’m not happy about that. My family loves homemade salsa and salsa was the primary reason I bought this thing. I imagined using it at least a dozen years. Well, one year is the life span of the cup. You’re better off buying a better food processor than trying to replace cups. The motor would probably last through a dozen cups or pitchers but the cost of replacements make it a terrible option.

I've had to replace the lid to the processor bowl twice. The quality of material used in this product is poor at best. The piece that secures the lid to the bowl is plastic and has snapped off three times now. I will not replace the part for the third time, I am looking for another brand.

We purchased 2 of these food processors from Ninja now. They work great until they break, which has now happened to each of them less than 6 months after purchase. The bottom literally separates, and it's obvious the plastic simply sheared off from torque pressure. We thought the first time was a fluke, so we got another. Sad to say, no fluke.

Honestly, after using this 1 time to chop vegetables, I don't know how I've lived without one of these! That alone, to me, was worth the price of purchase! The only problem I have, is deciding which of the million and one things I want to do with this little beauty. Very reasonably priced, and came with 2 32 ounce blending cups, which I have not seen ANYWHERE else. Clean up is a snap, and I've read you can put together pasta dough with this! My life was made much easier by my sweet husband, who bought it for me!

It seems to be hit or miss with the quality of this product. I've had the product for 7 months. The main container had a crack and began to leak. Ninja product support replaced it after I complained but they originally wanted to charge me for a replacement container. Next, the cup top (with the blade) connected to the motor base but wouldn't work (no options to blend lit up). They want to charge me for a replacement. I asked to speak with a manager and explained what I thought was a quality issue. He's now working with me and is making an exception to replace the defective part. Because of the unreliable quality of products, purchasing an extended warranty is necessary as a back-up.

Worked great, until it broke less than a year after purchase. The pro extractor blade assembly (for the single serve cup) seized up and started burning when I was using it. I am extremely careful to clean and dry this well with every use. Unfortunately, the limited warranty does not cover this part and the part is out of stock. So $160 down the drain since this is what I use daily. I loved this blender, but their warranty and accessories replacement has me looking for a better company. No more Ninjas for us.

I’m really disappointed in this for a lot of different reasons that might not matter to anyone else, but for the price…I had to return it. I talked myself out of buying it for about a year before splurging. Brought it home, unboxed it and decided to make a smoothie with fresh cut watermelon, ice, and mint. I followed a recipe from (I believe) the ninja website. The machine is LOUD. That would be fine but…it didn’t even chop the watermelon up, let alone the ice. Chunks of both. The cup is giant, honestly I don’t think I’d ever be able to finish a drink that took up half that cup. I mainly got it to make a protein fluff for breakfast with yogurt and cottage cheese. It couldn’t mix it up. Still giant chunks of cottage cheese. Tried to use the dough hook to make naan from ninjas website…half the liquid was underneath the connector for the dough hook. It was a nightmare to clean. Again, let me say it is LOUD. I’d be fine with that….if it worked better. I was also terrified the plastic containers would break if a piece of ice hit the side of something the wrong way. I returned it and I don’t miss it at all. It took up a lot of room in my cupboard, and a cheaper blender would do a better job.

Honestly, this thing blends like a champ. Frozen fruit, ice, even thick smoothie mixes disappear pretty fast. The big pitcher is handy when making drinks for a few people. Only downside is the noise, it's definitely not quiet. Still, it's been a reliable workhorse in my kitchen so far.
