Great value for the price, and a powerhouse little unit!
Color: Gray Size: 48 ounces
I was looking for a blender so that I could make some smoothies for my daytime eating (to make things easier and healthier), but didn't want to spend a fortune to get something that was easy to use, easy to clean, and a very good blender. A few friends of mine recommended a Ninja blender, so I decided to give this one a shot. I couldn't be happier with my choice! As a blender, I have to say this is by far the easiest to assemble, use, and clean that I've ever had access to. The blades go together in a second, and you just drop them down into the carafe onto the little peg to get them situated. For a typical smoothie, I toss in frozen berries, some ice cubes, a banana, some yogurt, and a little soy milk. The lid snaps on easily without having to play with it forever. Then just set the electrical component on top of the assembly and hold down the large (and only) button, and you're on your way! When everything's done whirring about, it pours nicely out the spout of the lid, and you can stick the whole thing in the fridge if you have some leftovers. Clean-up is amazingly simple, as well. Even when I use a soy protein powder, this thing practically rinses clean with just hot tap water. I've yet to need to scrub with any real effort to get it spotless, including the blades and lid. You can put it in the dishwasher, but it'll probably fair better if you wash it by hand. A few things you should keep in mind if you do purchase this blender: 1. The place where the electrical component attaches to the blade shafts can get spattered with the blender's contents if it's full enough, or if the mixture is thin enough. After using the blender, always check that little indentation on the electrical component and clean it immediately with a dry paper towel, cotton swab, or whatever else you have that'll fit in that area. If you let things dry up in that crevice, it can be hard to clean later. 2. The spout on the lid pours very well, but if there is anything on the rim of the spout when you go to snap it shut (as if to store leftover contents), then it will be spattered about your counter, wall, or shirt. Make sure you wipe that area nice and clean before closing the spout cover. 3. There is a tiny hole in the bottom of the blade shaft where it slides onto the peg inside the blender carafe. Make sure you have a pipe cleaner or thin wire brush (or something similar) to clean up inside that tiny crevice after use. I had a set of wire brushes meant for cleaning out straws and the spouts of sports bottles, and they work perfectly for this. 4. These blades are extremely sharp. Far sharper than those of any other blender I've used. Handle them with extreme care, unless you dislike having all the fingers you currently possess. 5. There is only one speed (Speed Awesome!) and you must hold down the button for it to blend, so you can't walk away from it after turning it on. You do have to stand there and keep the button down to have it continue blending for you. (Essentially, it only pulses.) Bottom line, I highly recommend this to anyone who needs a blender for a good price, and doesn't want to work too hard to clean it afterwards. It also comes with a food processor assembly, so you really can't go wrong! ... show more

Great bargain, works great!
Color: Black Size: 48 ounces
This is a great kitchen tool and does so much. I like the 3 pieces that can do different functions. I liked the older style with the "push down to activate" function, better. Very powerful and does everything needed. The price was a great value. I hope the carafes hold up better than the old style, though. ... show more

Don't second guess this, especially for the price! Just buy it. This unit replaced my old bulky kitchen aide food processor and my old bulky vitamix. Absolutely LOVE this addition to my kitchen. We use it to crush ice for margaritas, dice up veggies and onions for meals, and make smoothies. It's Fast and easy to operate. I have a tiny kitchen with not a lot of cabinet space and it fits perfectly. Thank you Ninja! ... show more

Perfect. Easy Cleanup.

Review Image by Brittany Koch Brittany Koch
This is a great little blender/processor. I needed a processor to make Mexican Corn Cake but I didn’t want to spend too much as I don’t have many uses to have a big one taking up space all the time. I got this one for $39. This set does not take up a ton of room and is very versatile. You can customize the blades in the small container as well as the pitcher. All of the plastic is nice and thick; there are no cheap feeling pieces in this set. I’ve also made smoothies with it and it crushed ice and frozen fruit with zero issues. I love that it is all dishwasher safe too, saves time on cleanup. Be careful during assembly because when they say those blades are sharp they are NOT joking! I didn’t even know I touched one of the blades when I was putting it together and I must have cut myself! So try to pick the blade part up by the stem. It’s loud like any other blender, but not obnoxious. You’ll definitely hear it in the other room, but it’s a blender so I would think most are going to be loud unless you have a vacuum sealed professional blender. ... show more

This item is great!!
Color: Black Size: 48 ounces
So far, I absolutely love this blender and food processor. I’ve been looking for one for a few weeks now that would meet my needs. I’ve had an old Hamilton Beach blender since I was married almost 50 years ago. It still works, but I don’t like having to mix everything in the big glass container and it’s hard to clean. This blender, food processor appeal to me because it came with three different sizes of containers with individual blades and covers for each one. This morning I made a smoothie in the smaller container and it worked perfect. Runs smooth and clean and it isn’t very loud. The tops have an and it isn’t very loud. The tops have a rubber ring around the opening and the top fits securely inside of the container so there are no leaks! Everything is easy to clean and they’re all dishwasher safe. If I want to make salsa or a margarita I can use the other two containers and I have an option of the size I want. You have to make sure that the power pod is seated correctly and then you push on it and you can either pulse it or let it run for a while, depending on what you are mixing and the consistency of blending you need. I’m so glad that I purchased this. I was not sure what I wanted. It was $59 and I got it in two days. I envision a lot of use and other reviews I read say that it lasts a long time. It is so much easier to use than my big blender. Having multiple sizes is very important to me. I’m sure that anyone that purchases this will be pleased! ... show more

Bought to replace an older one that went out. It is as pictured and works great. Gave it a five star because it was not in a ninja box and all the pieces were just thrown into an amazon box. So the motor piece was just rolling around in the box and the picture was scratched up since the blades are so sharp. Not sure why they took it out of the ninja box. Thank goodness the motor works with my old picture because i use this everyday. ... show more
