Great Basic Blender

This basic blender is reliable and problem free. Been using this for about a year, almost every day and it’s not let me down. I have a morning smoothie and it blends ingredients the way I like it - with a little texture vs. super smooth. I’ve also used it to blend soups and it’s well up to that task. What I love about it is clean-up, so much easier than a traditional blender.

I’ve always had very bad luck with blenders so I was reluctant to buy this but I’m very happy I took that chance. I LOVE it! Blends very smoothly and it actually blends the ice cubes, unlike MANY other blenders. Definitely would recommend this product!

Ninja Auto IQ

I absolutely could not function without this piece of equipment. The IQ pulverized the toughest vegetables into silk. I was so impressed. Goodbye juicer! I bought the complete system, blender, juicer, food processor that also comes with a dough kneading blade. I only regret that I did not buy the vegetable slicer bowl and blades, As then I would have had a complete kitchen prep station. Superb product! Ps: anyone hesitant about buying this product need not worry!

Better than a Vitamix!

I purchased a re-built Professional Series Vitamix for over $530. It was so loud, I had to leave the room while it was running and my husband begged me not to use it around him. The hot soups were foamy and not worth the time. The machine went back and I was happy to get my money refunded for something that wasn’t worth the price. For ages, my mom would often talk about her Ninja with the motor on the top. I had never seen one, only the machines with the bottom motors. She sent me one for Christmas but wa...more

For ages, my mom would often talk about her Ninja with the motor on the top. I had never seen one, only the machines with the bottom motors. She sent me one for Christmas but was worried since she knew I had just bought the pricey Vitamix. How could it compete, right? Well, this little machine out-did the Vitamix! It chops onions and veggies like I want, it makes smooth smoothies, and it is quiet and easy to clean. I am so thrilled! I’m telling everyone. I have a Bullet and it won’t chop a thing. It makes smoothies OK but it needs to run a long time. This Ninja makes the smoothies fast and grinds the ice without complaint. If I knew anyone getting married, this would be the gift I would give them. I love this machine and the price/value is stellar!

This is the best product I have ever purchased. The quality and price helped in my decision to buy it. I make smoothies everyday and salsa often, the kids love it and its healthy. You wont be disappointed with your purchase.

Great product

I have owned this model for about 6 months now and I use it all the time. It works fantastic and I have had no problems with it. (other than cutting myself a few times on the blades while cleaning). The only thing that I do not like about it is I wish there were other types of blades available for the food bowl part of the appliance (such as a shredding disk or slicing disc). Otherwise its a great product.

Wonderful Product!!!

I bought my Ninja Master Prep at Sears, a few years ago. I LOVE it and use it daily making breakfast shakes each morning. It chops ice, fruit, vegetables.. you name it, and still works great!! I’m just glad it is still out there to buy when mine finally wears out! I can also throw it in the dishwasher which is also nice. A++++++ blender!

The best product of it’s kind

This is a great all-round food prep appliance that I have ever used. I have the smaller prep bowl which makes this a complete unit now. I love it and use this several times a week for various food prep situations.

Like Whey protein base and go berserk from there, adding avocados, spinach, kale, chia & hemp seed, beets, celery, well, you get the idea. I had planned to nest in a VitaMix but I found the Ninja Master Prep a much more versatile unit capable of so much More, for so much Less, $$$! I have invested too much money with single purpose units but never have been as Pleasantly Pleased & Rewarded as I have been with My Ninja Master Prep! Thats just the tip of My Iceberg usage of food prep tools. Being a professional Chef most my life, I speak from years of Experience with kitchen gadgets and, readers This is No Gadget, it’s The real Deal in my Personal Home Kitchen! If I were to add anything to this unit, it would only be a nonslip grip surface to the motor head and, extra seals/gaskets and, a crevice cleaning tool for the hard to get to top and the blade & blade hole for perfect sanitizing. ”WOW,” what a Find for me.

I LOVE MY NINJA!!

I have had many other blenders and they always seem to mess up or you can’t clean them very well because the blade doesn’t come out. Since having this blender, I have been able to make all different kinds of recipes and I don’t have a problem cleaning it at all. I LOVE MY NINJA!! I will never go back to any other brand.

Very good product

I bought this at walmart and it was very cheap by the way makes good fruit smoothies and it makes peanut butter, dressings by the way, I even tried to chop carrots in it works great by the way. I registered this product over the phone and the lady was very nice by the way over the phone. And I can get rid of my gnc blender because it does not work. It even chops garlic to. By the way I am very happy with ninja by the way they have good products.

Ninja Master Prep

I purchased this item couple days ago. Works great. I had to figure out how to make the perfect blend. but once I did wow. Works much better then my now dead Magic Bullet. I had had for several years. Now I can make the items I love and enjoy. Totally worth the $40

Awesome!!

Hey from Canada! Just bought the Mega Prep yesterday to make ice cream and sno-comes for my granddaughters. What can I say- it’s a Ninja!! It’s great not to have to get the big Ninja blender out for little chopping and mixing. I also have the Ninja slow cooker system and it’s the best one I’ve ever had. (And that’s lots- my mom gave me my 1st s/c for a shower gift 36 yrs ago) if anyone is hesitating- don’t. You won’t regret buying ANY Ninja product. Now I’m waiting for the Nutri -Ninja to c...more

Great for smoothies

This product is great for smoothies and is done in less than a minute. Plus I can make 2 at a time. We have been using an old blender for years and I broke the glass container. I don’t know how this product works for other things but it is great for smoothies!!!!

I love my ninja... Yet I am not happy with the way the blade is made into two parts and wears out and the second blade quits turning... They should make the two blades permanently connected.

It is the perfect size for a small kitchen

I love this machine. It is the perfect size for a small kitchen - not taking up much space at all. But in the 6 weeks that I have been using it (twice daily) , I have broken (spiral fracture)the long shaft for the tall blender, and burned out the motor. Looking for parts for it - I discover that individual parts cost as much as a new blender. That sucks.

Bought my wife the Ninja at Sam's Club. Now I find myself helping in the kitchen. I love to play with this thing. It's really fun. I made some great turkey salad with some leftovers using this machine. It was a breeze. And it tasted great. Wonderful smooth texture.

I just got this for Christmas and have already used it several time. I've used it to make baby food and also some of my favorite dishes that require lots of chopping, shredding and pureeing. It is so easy to use and works quickly. I'm definitely getting one of these for my parents.

LOVE, LOVE, LOVE

I LOVE, LOVE, LOVE my Ninja Prep. I am a client and employee of a weight loss clinic and it has helped me meet and maintain my healthy goals. We have recommended the Ninja to all of our clients. It works awesome on our protien drinks, lo cal cheesecake and decaf coffee shakes. I've used my Ninja so much that I feel like I should replace the blades. Would love to get information about where to purchase new blades, so I can continue using the Ninja in my home.

It made snow cones so quickly

I live in Florida so we don't get snow for Christmas. It made snow cones so quickly, I used it to make a big bowl of snow for my son to play in. He built a little snow person and threw snowballs. For Christmas I plan to buy a big bags of ice so we can make snow for our yard.

I am throwing my bullet, choppers and cuisineart away! THANK YOU NINJA! Going to chop veggies for a tiny cubed salad..lol.

This is the best all around mixer/food processor I have ever used. It is fast and easy to use. It will chip ice in a second and grind raw boneless meat in a quick 1,2,3 hit of the on switch. I would recommend this to everyone. My kids are all grown and on their own and I want to get one for each of them. i love this machine.
